PowerColor Radeon HD 4870 Fails to Complete FurMark

Expreview has done some tests on the new Powercolor product, the Radeon HD 4870:


One of these tests is FurMark and the HD 4870 fails to complete one minute of FurMark’s stability test. Failure symptoms are VPU recovery message, red LED (on the PCB) that shines…

For one thing, BIOS limited fan speed too low, that results in a higher GPU temperature; For the other thing, it gets through 3DMark Vantage, but fails to complete FurMark test. We believe it’s the BIOS setting that causes these problems and asked PowerColor for a new BIOS, but the answer was not available yet.

Sapphire Radeon HD 4870 Review

Sapphire’s Radeon HD 4870 reviewed at Hardware Secrets.

Read the full review HERE.

In most scenarios Sapphire HD 4870 was between 20% and 30% faster than Sapphire HD 4850, but on some games like Quake 4 and Half-Life 2: Episode Two both cards achieved a similar performance, depending on the video configuration used.

Sapphire HD 4870 and GeForce GTX 260 achieved a similar performance in most scenarios. The only time that GeForce GTX 260 was faster than Sapphire HD 4870 was on Call of Duty 4 at 2560×1600 maxing out image quality settings (11% faster). In all other configurations on this game both cards achieved the same performance level.

InfraRed Photo Shows which Part of Your HD 4870 is Hot While Running FurMark

German Radeon user Tiesie have posted some Infra-red photo of his/her HD 4870 with Arctic Cooling Accelero S1. The sticker part is hot and keeping the reference red cooler base is no help for cooling. All these shots have been taken after 10~20min of FurMark.

I wonder if Tiesie has used FurMark in Xtreme Burning mode (currently command line but soon in the startup dialog box) or in standard mode…

TT-Hardware nous propose un article comparatif des performances entre la GeForce GTX 280 et les Radeon HD 4870/4850.

Lire le test complete ICI.

La GeForce GTX 280 confirme qu’elle est bien la carte de tous les superlatifs : la plus grosse, la plus complexe, la plus performante mais aussi la plus encombrante, la plus bruyante, la plus gourmande et surtout la plus chère (de 460 € à plus de 500 €). Des points faibles qui pèsent lourd par rapport aux avantages surtout que la Radeon HD 4870 vient jouer les trouble-fêtes. En effet, si la Radeon HD 4870 est un peu en retrait par rapport à sa rivale, elle est surtout beaucoup moins chère (230 €) et nettement plus discrète. Sa seule contrepartie est une consommation importante au repos. La Radeon HD 4850 (moins de 160 €) est la révélation de ce comparatif : elle ne souffre d’aucun point faible. Ses prestations la mettent en concurrence avec la GeForce 8800 GTS OC MSI ainsi que les GeForce 9800 GTX et GTX+ (220 à 230 €). Ces dernières sont au moins 30% plus chères et nettement plus bruyantes et donc dans l’état actuel des choses sans le moindre intérêt ! Seules les GeForce 8800 GTS 512 Mo peuvent encore tirer leur épingle du jeu en raison d’un prix inférieur à 200 € et un silence de fonctionnement plus qu’appréciable. Particulièrement intéressante à son lancement, la GeForce 9600 GT est aujourd’hui caduque.

Radeon HD 4850 and 4870 CrossfireX Performance Test

Since Radeon series 4800 cards offer so much value, it might even be interesting to pair them in CrossfireX mode. AMDs ATI solution can be paired and matched as well. So today Guru3D has placed several cards together in CrossfireX mode.

No kidding it is sick how much performance these cards combined can push, the 2-way GPU scaling is just really superb. Crossfire with two series 4800 cards definitely makes more sense than NVIDIA’s high-end SLI money wise.

Radeon HD 4850

FurMark has been used to stress Radeon HD 4870 and 4850’s GPUs.

Final words
So, numbers can talk for itself. With the price tag $199(HD 4850) and $299 (HD 4870), RV770 is the BEST bang for the buck. Compare to GTX 260, A $299 only HD 4870 is a smarter choice. Yes, using this kind of word seems quite biased, but if you read all numbers from our review you will see my point.

Compare to GTX 260, HD 4870 is only 3/4 of its price while test items show the card have almost the same firepower!

HD 4850’s rival is 9800GTX, and we can see while their price keeps the same, HD 4850 have more than 15% leading.
