3DMark vantage shows a greater difference between results than the older Mark06. XFX 670M XX beats Gainward’s reference card by 6% and does the same to HD 4870 by 28%. Mark 06 says that there’s only a 4% performance difference between the fastest GTX 280 and Sapphire HD 4870.

In Mark06, MSI R4850 loses to Geforce 9800 GTX by 6.7%, but outperforms it by 4% in Vantage. HD4870 was better than this single slot card by 17% in Vantage and 12% in 3DMark06.

MSI ran on par with Diamond HD 4850 card, but both cards feature reference design and speed.

Company of Heroes sees ATI failing to beat Nvidia GTX 260. We ran the tests in Vista 32, but Radeon HD 4870 tested under Windows XP outran the GTX 260. The fastest card in this game was XFX with their overclocked GTX 280, and at 1280x1024 4xAA i 8xAF it beat HD 4870 by almost 100%. Gainward managed to outperform Radeon HD 4870 by 90% with their reference GTX 280.

With their overclocked GTX 260, EVGA closely followed GTX 280 and it beat the reference GTX 260 by about 10%. 2048x1536 with 4xAA and 8xAF shows that EVGA’s overclocked card is capable of much more and it beats the reference GTX 260 by 20%. At the same resolution Radeon HD 4870 ran slower by about 30%.

MSI 4850, just like its big brother Radeon HD 4870, loses to reference GTX 260 cards, but bear in mind that for the price of around €125 – this is one hell of a score. At higher resolutions with Antialiasing on, it loses to HD 4870 by only 30%. It most resolutions it ran a bit faster than Diamond’s card except in the highest one where it beat it by 5% (1 fps), which is the biggest advantage we’ve seen during testing.

Call of Juarez sees Radeon HD 4870 and Radeon HD 4850 holding well versus reference GTX260 and GTX280. Sapphire Radeon HD 4870 even manages to beat GTX 280 by up to 12%, but it ran on par with XFX 670M. XFX 670M is up to 11% better than reference GTX 280.

ATI is simply good at this game, so not even overclocked EVGA GTX 260 FTW could overthrow HD 4870. EVGA followed Gainward GTX 280 closely.

Gainward GTX 260 ran on par with MSI R4850. Compared to HD 4870 GDDR5, MSI was about 29% slower.

Crysis put all the games through their paces, so at 1600x1200 4xAA 8xAF we see enough frames for gaming, but barely anything to brag about. XFX 670M XXX ran the fastest and scored 35fps. It outperformed HD 4870 by 29%, and EVGA GTX 260 FTW by 20%. At the same resolution, EVGA scored a playable framerate, whereas we couldn’t say the same for the reference GTX 260. EVGA again outperformed the reference GTX 260 by 11% and HD 4870 by 7%.

MSI R4850 shows its teeth and we see it beat 9800 GTX by 16%. It loses to HD 4870 by 20% and 28% at the highest tested resolution.

We’ve seen what reference HD 4850 card can do and we’ve already mentioned that by supplying their D.O.T. tool, MSI is pushing for more user friendly overclocking. Let’s see what predefined speeds this tool provides.

We have 6 overclocking settings and they’re not too far apart from each other. If you set the highest rank “Commander”, the core will run at 700MHz and the memory at 1112MHz. Just a reminder – reference speeds are 625MHz core and 933MHz memory.

With an overclocked card, we managed to improve Vantage results by 9%, which is not too shabby.

Conclusion

ATI did a good thing by optimizing the existing architecture, instead of the usual routine where you just add more of what you’ve got. Although HD 4800 cards feature 800 shader processors, which is 2.5 times more than HD 3800, many things are fixed and optimized. FSAA finally runs nicely so RV770 will let you enjoy it in its full glory. The new HD 4800 generation brings great performance and incredible bang for buck in this price segment.

Today, we’ve seen MSI’s R4850 in action, and although running at default speeds it still scored nicely. It’s evident that €125 can’t buy you a better card than this baby. We don’t really like the reference cooler that heats up significantly, and any serious overclocking should be done with a better cooler. The good thing is that it’s quite similar to the coolers in previous generation, so you'll probably be able to get a replacement easily, should you need one. Still, the cooler is not too loud and it keeps the GPU temperatures at maximum 85 degrees.

MSI R4850 is a card that you shouldn’t pass by, especially knowing that €125 will buy you a card that will serve you well and provide unbelievable performance within this price segment.
