AMD/ATI has released two new high-end graphics chips recently, Radeon HD 4870 and Radeon HD 4850, known by the codenames RV770 XT and RV770 PRO, respectively. As you can guess by the numbers, HD 4850 provides a lower performance compared to HD 4870. In this review we will benchmark HD 4850 from Sapphire and compare it to its main competitors from NVIDIA. Is this video card a good buy? Check it out.
Sapphire HD 4850 follows AMD/ATI’s reference model both on its physical aspect as in specifications: the graphics chip runs at 625 MHz with its memory being accessed at 993 MHz (real clock) through a 256-bit memory interface. Since GDDR3 memories transfer two data per clock cycle, the memory achieves a performance as if it were working at 1,986 MHz, delivering a maximum transfer rate of 63.5 GB/s.
Both new chips are based on DirectX 10.1 (Shader 4.1) architecture, where all processing units inside the graphics chip are generic, being able to process any kind of vector (pixel shader, vertex shader, etc). What is really impressive about these two new chips is that they both have 800 processing units inside the chip. We will provide a short table comparing the specs from this new video card with the specs from its main competitors. Before that, let’s take an overall look at Sapphire HD 4850.
[nextpage title=”Introduction (Cont’d)”]
We removed the video card cooler to take a look. As you can see in Figure 4, the cooler is 100% made of copper, which is great, as this material dissipates heat better than aluminum.
In Figure 5, you can see the video card without its cooler. It uses eight 512-Mbit Qimonda HYB18H512321BF-10 GDDR3 chips, making its 512 MB memory (512 Mbits x 8 = 512 MB). These chips have a maximum real clock rate of 1 GHz (1 ns, 2 GHz performance), so on this video card they are practically running on top of their maximum spec.
In Figure 6, you can see all accessories and CDs/DVDs that come with this video card, which includes a 2 GB USB drive (limited time offer). With the accessories that come with this card you can convert the video output to VGA, HDMI, component video and composite video, plus the DVI and S-Video connectors already present on the product.
This video card comes with three games inside a DVD called “Ruby ROM 1.1”: Call of Juarez, Dungeon Runners and Stranglehold. Programs that come with this video card include CyberLink DVD Suite (PowerProducer 4, PowerDirector 5 Express, Power2GO 5.5, Mediashow 3 and trial versions of PowerBackup 2.5, PowerDVD Copy and LabelPrint 2), Cyberlink Power DVD 7,3DMark06 Full, EarthSim and GameShadow.
Now let’s compare the Radeon HD 4850 specifications to its main competitors.
[nextpage title=”More Details”]
To make the comparison between Sapphire HD 4850 and the other video cards we included in this review easier, we compiled the table below comparing the main specs from these cards. If you want to compare the specs of Radeon HD 4850 to any other video card not included in the table below, just take a look at our NVIDIA Chips Comparison Table and on our AMD ATI Chips Comparison Table.
|GPU||Core Clock||Shader Clock||Processors||Memory Clock||Memory Interface||Memory Transfer Rate||Memory||Price|
|GeForce GTX 280||602 MHz||1,296 MHz||240||1,107 MHz||512-bit||141.7 GB/s||1 GB GDDR3||USD 620 – 660|
|GeForce 9800 GX2||600 MHz||1,500 MHz||128||1,000 MHz||256-bit||64 GB/s||1 GB GDDR3||USD 420 – 550|
|GeForce 9800 GTX||675 MHz||1,688 MHz||128||1,100 MHz||256-bit||70.4 GB/s||512 MB GDDR3||USD 200 – 300|
|Rsdeon HD 4850||625 MHz||625 MHz||800||993 MHz||256-bit||63.5 GB/s||512 MB GDDR3||USD 195|
|Sapphire Atomic HD 3870 X2||857 MHz||857 MHz||320||927 MHz||256-bit||59.33 GB/s||1 GB GDDR3||–|
|Radeon HD 3870||776 MHz||776 MHz||320||1,125 MHz||256-bit||72 GB/s||512 MB GDDR4||USD 135 – 240|
As you can see the main difference between the new Radeon HD 4850 and its competitors is the amazing number of processing units, 800 against 128 on GeForce 9800 GTX, for example.
In order to compete with Radeon HD 4850, NVIDIA reduced the maximum suggested price (MRSP) of GeForce 9800 GTX to USD 199, so Radeon HD 4850 and GeForce 9800 GTX are, today, on the same price range. At least officially – think about it, if you are a reseller and has your stock loaded with USD 300 video cards, would you lower them to USD 200 just because NVIDIA told you so? One week ago GeForce 9800 GTX was quoted between USD 270 and USD 355. NVIDIA also has launched a “new” high-end video card, GeForce 9800 GTX+, which is basically an overclocked GeForce 9800 GTX.
Some important observations regarding this table:
- All NVIDIA chips are DirectX 10 (Shader 4.0), while all AMD/ATI chips are DirectX 10.1 (Shader 4.1).
- The memory clocks listed are the real memory clock. Memory clocks are often advertised as double the figures presented, numbers known as “DDR clock.”
- GeForce 9800 GX2 and Radeon HD 3870 X2 have two GPU’s. The numbers on the table represent only one of the chips.
- All video cards included on our review were running at the chip manufacturer default clock configuration (i.e., no over
clocking), except Sapphire Atomic HD 3870 X2. The official core clock for Radeon HD 3870 X2 is 825 MHz, while the official memory clock is 900 MHz. So this card was a little bit overclocked. We couldn’t reduce these clocks to their reference values and since we hadn’t any other Radeon HD 3870 X2 available we included this video card anyway.
- Prices were researched at Newegg.com on the day we published this review.
- We couldn’t find Sapphire Atomic HD 3870 X2 for sale. This model will be more expensive than cards from other vendors based on the same GPU because it features water cooling. Just for you to have an idea, prices on the regular Radeon 3870 X2 are quoted between USD 300 and USD 380.

Resolutions and Image Quality Settings
Since we were comparing very high-end video cards, we ran all our tests under three 16:10 widescreen high resolutions: 1680×1050, 1920×1200, and 2560×1600. We always tried to run the programs and games in two scenarios for each resolution, one with low image quality settings and then maxing out the image quality settings. The exact configuration we used will be described together with the results of each individual test.
We adopted a 3% error margin; thus, differences below 3% cannot be considered relevant. In other words, products with a performance difference below 3% should be considered as having similar performance.
[nextpage title=”3DMark06 Professional”]
3DMark06 measures Shader 3.0 (i.e., DirectX 9.0c) performance. We run this software under three 16:10 widescreen resolutions, 1680×1050, 1920×1200, and 2560×1600, first with no image quality enhancements enabled – results we call “low” on the charts and tables below –, then setting 4x anti-aliasing and 16x anisotropic filtering.

[nextpage title=”3DMark Vantage Professional”]
3DMark Vantage is the latest addition to the 3DMark series, measuring Shader 4.0 (i.e., DirectX 10) performance and supporting PhysX, a programming interface developed by Ageia (now part of NVIDIA) to transfer physics calculations from the system CPU to the video card GPU in order to increase performance. Mechanical physics is the basis for calculations about the interaction of objects. For example, if you shoot, what exactly will happen to the object when the bullet hits it? Will it break? Will it move? Will the bullet bounce back? Notice that we didn’t upgrade the PhysX to the latest version, which would make the physics calculations for CPU Test 2 to be made by the GPU instead of the CPU on NVIDIA video cards (since we aren’t considering CPU or 3DMark scores this change wouldn’t produce any increase in our results anyway).
We ran this program at three 16:10 widescreen resolutions, 1680×1050, 1920×1200, and 2560×1600. First we used the “Performance” profile, and then we used the “Extreme” profile (basically enabling anti-aliasing at 4x, anisotropic filtering at 16x, and putting all detail settings at their maximum or “extreme” value. The combination of 2560×1600 resolution with extreme settings didn’t produce reliable results according to the program, so we aren’t going to add them here. The results being compared are the “GPU Scores” achieved by each video card.

[nextpage title=”Call of Duty 4″]
Call of Duty 4 is a DirectX 9 game implementing high-dynamic range (HDR) and its own physics engine, which is used to calculate how objects interact. For example, if you shoot, what exactly will happen to the object when the bullet hits it? Will it break? Will it move? Will the bullet bounce back? It gives a more realistic experience to the user.
We ran this program at three 16:10 widescreen resolutions, 1680×1050, 1920×1200, and 2560×1600, maxing out all image quality controls (i.e., everything was put on the maximum values on the Graphics and Texture menus). We used the game internal benchmarking feature, running a demo provided by NVIDIA called “wetwork.” We are putting this demo for downloading here if you want to run your own benchmarks. The game was updated to version 1.6.

Crysis is a very heavy DirectX 10 game. We updated this game to version 1.2.1 and used the HOC Crysis Benchmarking Utility to help us collecting data. Since we don’t think the default demo based on the island map stresses the video card the way we want, we used the HOC core demo available with the abovementioned utility. We ran this demo under three 16:10 widescreen resolutions, 1680×1050, 1920×1200, and 2560×1600, first with image quality set to “low” and then with image quality set to “high.” Since all video cards achieved a number of frames per second below 10 at 2560×1600 with image details set to “high,” we are not including this test as the results aren’t reliable. We ran each test twice and discarded the first result, as usually the first run achieves a lower score compared to the subsequent runs since the game loses time loading files. The results are below, in frames per second (FPS).

With so much data presented in the previous pages, we think we should summarize our review answering two questions: how is Sapphire HD 4850 compared to Radeon HD 3870 – once the most high-end video card from AMD/ATI – and how is Sapphire HD 4850 compared to GeForce 9800 GTX, especially now that NVIDIA is promoting a price cut on this model in order to make it a competitor to HD 4850.
AMD raised the performance of the new Radeon HD 4850 to a completely new level. Sapphire HD 4850 was between 6% and 91% faster than Radeon HD 3870 during our tests, depending on the game, resolution and image quality settings. The highest differences were found when we increased image quality. You can see the complete breakdown in the previous page.
We saw a good battle between Sapphire HD 4850 and GeForce 9800 GTX. Here is the breakdown.
We saw Sapphire HD 4850 being faster than GeForce 9800 GTX on two programs: 3DMark Vantage (between 26% and 35% faster) and Quake 4 (between 7% and 31% faster).
We saw Sapphire HD 4850 and GeForce 9800 GTX achieving the same performance level on Call of Duty 4, Crysis and 3DMark06 with image quality settings enabled (with image quality settings disabled, GeForce 9800 GTX was between 8% and 11% faster).
And we saw GeForce 9800 GTX being faster than Radeon HD 4850 on Unreal Tournament 3 (between 17% and 53%) and on Half-Life 2: Episode Two (between 15% and 22%, however both cards achieved the same performance at 1920×1200 with no image quality settings enabled and Sapphire HD 4850 was 7% faster than GeForce 9800 GTX at 1680×1050 with no image quality settings enabled).
So we have to call it a technical tie, because which one is faster will depend on the game. On the two of the heaviest games around today – Crysis and Call of Duty 4 – both cards achieved similar performance.
Then comes pricing. On this aspect Sapphire HD 4850 has, today, the biggest advantage, even with NVIDIA pushing their partners to drop GeForce 9800 GTX’s price down to USD 200. This model from Sapphire can be found around USD 195 and you can buy it on NewEgg.com for USD 175 after a mail-in rebate. Even though the cheapest GeForce 9800 GTX was being sold by USD 200 on the day we published this review, you could find GTX models being sold as high as USD 300, with most models being sold by USD 250. As we mentioned before we doubt resellers will drop their prices just because NVIDIA wants them to.
So unless you only play Unreal Tournament 3 or Half Life 2 we honestly believe that Sapphire HD 4850 is the video card that brings the best cost/benefit ratio for the savvy user looking for a high-end video card: it costs at least half the price of GeForce 9800 GX2, GeForce GTX 260 and GeForce GTX 280 and still brings a high-end gaming performance to your PC.
A final trick: at this time Radeon HD 4850 will only run stable if you install Catalyst 8.6 drivers and a hotfix made available by AMD.
