ATI Mobility Radeon HD 5830- a graphics card with support for DirectX 11, developed by AMD. The HD5830 is technically a lower frequency HD 5850, but it does not support the GDDR5 graphics memory standard. Therefore, a 128-bit memory bus coupled with DDR3 memory can cause performance degradation. Like all cards in the ruler Mobility HD 5800 The HD 5830 is based on the HD 5770 (RV840 chip).

The Mobility 5830 memory interface is formed from two 64-bit controllers leading to a 128-bit memory bus. The type of memory used is DDR3 with a capacity of up to 1024 MB. Due to the small bandwidth bus and the lack of the possibility of installing GDDR5, the performance of the card may not be as high as we would like.

HD 5830 uses 800 MADD cores (called stream processors) that form 160 5-dimensional groups. The 5830 has hardware support for all DirectX 11 features - tessellation, no sorting transparent polygon rendering (OIT), improved filtering and shadow rendering, improved post-processing, and improved HDR Texture Compression. In addition, the chip has 16 ROP units, 40 TMU units, and 40 TAU units.

In series HD 5000 has also been improved general processing(The HD4000 series has not been optimized for this task.) Therefore streaming performance ATI Radeon HD 5830 for DirectCompute 11 and OpenCL applications should get better.

3D performance Mobility HD 5830 should be at the class level gaming video cards and, therefore, all modern games released in 2009 should run fluently and without delays. Highly demanding games like Crysis won't go for maximum settings however, most games shouldn't slow down.

Series Mobility Radeon HD 5000 has an improved video processor (UVD2) for decoding HD quality video files. At the same time, video cards of this series can simultaneously decode two HD video streams (for example, Blu-Ray picture-in-picture) if the memory bus bandwidth allows (only for GDDR5, and probably not possible for HD5830). With the proliferation of the Flash 10.1 Beta player, the HD 5000 series graphics card is also capable of accelerating Flash HD video processing (this format is used, for example, on YouTube).

One more unique feature card series HD 5000 is their ability to transmit audio files in HD format (like Dolby True HD or DTS HD Master Audio), up to 8 channels and 192 kHz / 24 bit, via HDMI 1.3a. Same as the HD 5000 series for stationary computers, Mobility HD 5830 Supports Eyefinity technology, which allows up to 6 monitors to be connected to the graphics chip at the same time. Of course, it depends on how each specific manufacturer has implemented this moment. Regular laptop Supports three screens that can be used simultaneously (internal and two external).

The power consumption of the card is 24 W (according to AMD), which is pretty low. Consequently, this video card can be used in 15 "-16" notebooks, where the internal components are located more compactly, and there is no such powerful cooling system as in notebooks with a larger diagonal.

As you know, on this moment AMD has a leading position in the DirectX 11 graphics card market. The company's Evergreen line of graphics cards can satisfy the needs of almost any user who wants to taste all the delights the latest technology... Despite the fact that the retaliatory move of AMD's main competitor, NVIDIA, is scheduled to release the GF 100 chip at the end of next month, AMD has already filled a small gap in ATI's line of video cards. On February 25, 2010, AMD introduced new video card ATI Radeon HD 5830, which took the place of the missing link between the ATI Radeon HD 5770 and ATI Radeon HD 5850. The new product has the same GPU as other models in this series, and is a very attractive middle-end graphics card for hobbyists computer games having a limited budget. Considering the price, which should not exceed $ 250, the evaluation of the performance of this model is of great interest.

Considering that we could not get the reference ATI Radeon HD 5830 video card, we decided to test the Sapphire Radeon HD 5830 video card. This video card, according to the numerical index, is the youngest of the series of video cards based on the Cypress GPU.

Architecture of the tested video cards

	Radeon HD 5850	Radeon HD 5830	Radeon HD 5770	Radeon HD 4890	GeForce GTX 275
Stream Processors	1440	1120	800	800	240
Texture blocks	72	56	40	40	80
Raster Operation Blocks (ROPs)	32	16	16	16	28
Core frequency (MHz)	725	800	850	850	633/1404
Memory frequency (MHz)	1000	1000	1200	975	300/600
Memory bus	256 bit	256 bit	128 bit	256 bit	448 bit
Memory bandwidth (GB / s)	128	128	776,8	124,8	127
Maximum power consumption	1151 Wt	175 watts	1108 Wt	190 watts	219 watts
Estimated price	$310	$250	$159	$200	$249

From the presented table, you can already get a fairly clear idea of the new product. It would seem that the new Radeon HD 5830 should be much faster and more powerful than the Radeon HD 5770 due to an almost double increase in memory bandwidth and a third more streaming cores. On the other hand, a 22% decrease in the number of streaming cores could well be offset by a 10% increase in GPU clock speed. Do you think AMD introduced an analogue of the Radeon HD 5850 for $ 250? No matter how it is! Note that it is also distinguished from the Radeon HD 5850 by a two-fold reduction in the number of raster operations units (ROPs). Shader processing is performed at the level of the Radeon HD 5850, but it also cannot quickly display the resulting pixels on the screen, which makes it closer to the level of the Radeon HD 5770 and Radeon HD 4890.

External examination of the Sapphire Radeon HD 5830 video card

The Sapphire Radeon HD 5830 Modern Warfare 2 Edition comes in a black cardboard box that contains a description of all its benefits, such as DirectX 11 support, HDMI, Windows 7 compatibility, etc. Inside the box is a ribbed container, in the middle of which lies the video card itself, packed in an antistatic bag. There is another container under the container with the video card - a small box in which the adjacent equipment is located. Opening it, we found a manual, a CD with drivers, power adapters, a DVI-VGA adapter, a CrossFire bridge, and a coupon for downloading the Call of Duty game.

The video card is equipped with a fairly solid cooling system, enclosed in a black casing. The graphics processor is cooled by an 80mm fan, which, it should be noted, does its job perfectly, creating almost no unnecessary noise. When tested under load, the temperature of the Sapphire Radeon HD 5830 was the lowest among the tested video cards, confidently staying at 65 degrees. However, the presence of unused holes for the cooling system on the video card makes it clear that this cooling system is not a reference one.

On the front side of the video card there are four modern ports for connecting a monitor, two of which are DVI, and one HDMI and DisplayPort. On the back side there are two connectors for connecting an additional power supply, the connection of which is mandatory for the video card to work.

Overclocking

Considering that the Radeon HD 5830 already operates at higher frequencies, we did not hope for significant overclocking of this model. The Sapphire Radeon HD 5830 video card in stable operation did not reach the 875 MHz limit frequency allowed in Catalyst Control Center... The maximum frequencies that we managed to reach before the video card lost stability were 870 MHz (core) and 1200 MHz (memory).

Tests

Crysis warhead

The video card showed a result comparable to the results shown by the solution from NVIDIA. As expected, the performance is very close to that of the Radeon HD 4890.

Far cry 2

A less demanding game engine allowed Sapphire Radeon HD 5030 to outrun its competitors on the GTX 275 chip. Nevertheless, it clearly falls short of the closest relative of the Radeon HD 5850.

Resident evil 5

Here the new product is even ahead of the younger model, which once again suggests that the prices of the Radeon HD 4890 video cards correspond to their quality, and the Radeon HD 5770 also looks good.

3DMark Vantage

According to the 3DMark Vantage results, the Sapphire HD 5830 performed well, the overclocked version beat even the older model. Nevertheless, do not forget that this is a synthetic test, and in real conditions the results differ significantly.

Conclusion

The video card Radeon HD 5830 worthily took an empty place in the line of video cards with support for DirectX 11. Thus, AMD has expanded its assortment with another powerful video card competitive in its price category, which has come out to replace the disappearing from the market Radeon HD 4890.

The similarity of the Sapphire HD 5830 video card we tested with the Radeon HD 4890 is undeniable. This is reflected not only in the price close to the HD 4890, but also in almost identical capabilities provided by the new product. It should be noted that the advantages of a video card include not only performance and competitive price. This also includes a fairly quiet mode of operation of the Sapphire Radeon HD 5830, despite the powerful cooling system. Plus, it consumes less power than the Radeon HD 4890, both under load and without.

The video card lends itself to overclocking rather poorly, which is not surprising, because the GPU already operates at higher frequencies. Nevertheless, even a relatively small increase in frequency, obtained by us, brought Sapphire Radeon HD 5830 closer to the older model - Radeon HD 5850. When choosing between these two models, it should be borne in mind that the difference in price is only $ 60, and the number of raster operations units (ROP) in the representatives of the Radeon HD 5830 is reduced quite significantly.

The undisputed advantages of the Radeon HD 5830 include the provided advantages of the Radeon HD 5000 line, which make it even more attractive. There is the ability to play on three Eyefinity monitors, the ability to output high-definition audio encoded via HDMI, support DirectX technology 11, with the possibility of tessellation and shaders version 5.0.

The only drawback of the Radeon HD 5830 is the price gap with the Radeon HD 5770, which is about $ 80. However, a twofold increase in memory bandwidth in some cases significantly increases the performance of the Radeon HD 5830 and makes it possible for it to look pretty decent against the background of the Radeon HD 5770.

Ultimately, the price advantage can only be judged a few weeks later, after the appearance of a range of solutions based on the Radeon HD 5830 on the market and NVIDIA's response (the release of the GF100, which is scheduled for the end of March).

About six months ago, AMD, or rather, its graphics division AMD Graphics Products Group, once an independent ATI, introduced the world to a new generation of ATI 5000 Series video cards. It brought us hardware support new version API DirectX 11, shader model 5.0, tessellation, the impact of which on image quality we examined in our first review of the line and, of course, a new benchmark for performance in 3D graphics.

Thus, AMD instantly became the "king of the hill" of the video accelerator market, completely occupying the top, because at that time the competitor in the person of NVIDIA could not oppose anything in response. And although until recently the five-thousandth series of radeons was well equipped with video adapters of various power (and most importantly - cost), there was a big gap between the HD 5770 and HD 5850. The first of them could be purchased in Moscow retail for an average of 5000r, and the second cost exactly twice as much, about 10,000 rubles. And while NVIDIA was doing its best to somehow catch up with the competitor, ATI continued to work diligently trying to give customers the maximum freedom to choose high-performance video adapters at affordable prices.

As you may have guessed, this review will be devoted to the newcomer in the line of 58xx graphics accelerators - the Radeon HD 5830. We will look at the new product externally, check the performance and overclocking capabilities. But first things first.

Both in terms of price and level of performance, the difference between them came out quite large. Some intermediate model was required, which, moreover, could finally completely replace the old single-chip flagship of the company represented by the Radeon HD 4890.

Without wasting energy on the development of a new GPU, AMD has done quite simply and released another stripped-down version of the RV870. But unlike the popular Radeon HD 5850, the new video adapter came out as a real "stub". Of the 20 SIMD cores of a full-fledged Cypress, the Radeon HD 5830 has only 14, i.e. instead of 1600 universal stream processors, the junior model costs 1120. Accordingly, the number of texture units has decreased to 56 (4 per SIMD core). As you can see, the number of computing units has decreased by as much as 42%. And the number of rendering units was cut in half - to eight. Just like the RV840 or the old RV770.

With such characteristics, you should not initially count on a high level of performance. But if we compare with the old solutions of the Radeon HD 4800 series, the new accelerator Radeon HD 5830 is still slightly better. The advantages over the Radeon HD 5770 are even greater, because the latter is equipped with a 128-bit memory access interface, while new card there is still a full-fledged 256-bit bus.

To slightly compensate for the huge number of disabled computing units, the operating frequency of the core is set at 800 MHz, which is 10% higher than that of the older Radeon HD 5850, but lower than that of the top-end Radeon HD 5870 (850 MHz). But the GDDR5 memory operates at the same 4 GHz as the Radeon HD 5850. Taking into account the good overclocking potential of the RV870 and the new generation GDDR5 chips, we can still hope for a good overclocking relative to the initial characteristics.

In terms of power consumption, the Radeon HD 5830, unfortunately, is not happy with its low performance against the background of its fellows. According to official figures, the peak power consumption of this adapter is even slightly higher than that of the Radeon HD 5850. However, things are not so bad if we take into account the old Radeon HD 4890s, which are even more “appetites”.

But whether the Radeon HD 5830 will be able to compete with the old solutions, we will just try to find out based on the results of our tests. But first, let's take a look at the real product of this series.

We got an OEM video adapter from Sapphire. The card is packed in a simple bubble bag with a set of the following accessories:

adapter DVI / D-Sub;
power adapter "molex-PCI-E";
CrossFire bridge;
CD with drivers.

The graphics accelerator is completely different from typical video cards of this series, standing out both in the PCB design and unique system cooling.

The video card is equipped with two DVI connectors, one HDMI and one Display Port.

A large (if not a huge) fan of the cooling system over the entire width of the board (90 mm) with an original curved blade shape catches the eye.

The radiator is not very large. But the whole structure is pierced with five heat pipes.

The tubes are slightly flattened at the base and soldered onto the copper plate of the heat sink.

A separate simple finned radiator is provided for cooling the elements of the power supply circuit.

The board itself looks like this:

The main difference from the reference lies in the redesigned power subsystem. Sapphire HD5830 1GB GDDR5 is based on R2J20602 DrMOS chips manufactured by the Japanese company Renesas. Such microcircuits are usually used in motherboards, and DrMOS from Renesas are used in expensive top-end products, for example, the MSI 790FX-GD70 uses the R2J20604.

The RV870 graphics chip runs at its intended 800 MHz.

The board contains Samsung K4G10325FE-HC04 GDDR5 microcircuits with an access time of 0.4 ns, so you can count on an effective 5 GHz instead of the nominal 4 GHz.

To repeat all of the above, a screenshot of the CPU-Z program with the characteristics of the Radeon HD 5830 video card.

In 2D, the frequencies are reduced from 800/4000 MHz to 157/1200 MHz.

The cooling system has demonstrated excellent efficiency. In the Fur Rendering Benchmark stress test at a resolution of 1680x1050, the chip temperature did not exceed 66 degrees Celsius (at 21 ° C indoors). At 44% fan RPM it's easy excellent result... In simple 3D applications (i.e. real games), the peak temperature was even lower, and the fan speed did not exceed 40% of the maximum (about 1500 rpm), while the noise level was minimal. In idle mode, the fan is practically silent, its speed remains within 36% (1360 rpm).

In terms of overclocking, the Sapphire video card did not disappoint us either. Unlike the reference models of the HD 5800 series, this specimen does not have the ability to programmatically control the GPU voltage, which, however, did not prevent it from achieving full stability at a frequency of 960 MHz (20% higher than the nominal). Samsung memory also demonstrated excellent overclocking capabilities and complete stability at an effective frequency of 5512 MHz (37% higher than the nominal and 10% higher than the capabilities of the microcircuits themselves).

It should be noted that for overclocking we did not change the native CO, but the fan speed increased to 85%, which was fraught with a very high hum, and such a mode cannot be called practical. But initially we ran all tests in automatic mode fan speed control. True, the card could not withstand the intense load and after five hours of testing, minor problems began. After letting it cool down for five minutes, we set higher revs and passed all tests at the same frequencies without any problems. So, in practice, for everyday use, you will either have to limit yourself to slightly lower frequencies, or still sacrifice acoustic comfort and slightly raise the fan speed. But even the fact that, with significant overclocking, the native cooler was able to provide long-term operation in the standard "quiet" mode, speaks of its high efficiency.
