Radeon R700 aka 4870x2

PCGH proves micro stuttering on the Radeon HD 4870 X2 - http://www.pcgameshardware.com/aid,...es_micro_stuttering_on_the_Radeon_HD_4870_X2/

Conclusion: micro stuttering
It's not over, yet. Future drivers might make the more popular games run smooth, but a general solution is not insight. As you can see it is a grief problem. Since why should you pay twice the price just to "experience" the same fps as with a less expensive graphics card? The same thing can be said about the Nvidia solution Geforce 9800 GX2 and all graphics cards that can be connected via SLI, too. The Californians find it equally difficult to find a proper solution.

Since we've tested many games, we can say that micro stuttering occurs in Half-Life 2, Crysis, Race Driver Grid, Need for Speed Carbon, TES4: Oblivion and 3D Mark Vantage. To be fair, we have to admit, it takes such demanding settings to bring the HD 4870 X2 to her knees. But in the future, with new games, the fps will decrease. Not later than that time the problem will rise again, while those who use big screens or those fans of FSAA will have to deal with the problem all the time.

Noob pitanje:

To "mikromucanje" vazi samo za dual-gpu karticu? Dve 4870 u SLIu nemaju takvih problema? Nikako da skontam gde se SLI uklapa u celu pricu o X2ci...

Taj problem imaju i SLI i CF, kao i dual-gpu kartice.

ispada da kupcima CF, SLI, X2 micro sulttering uospte ne smeta jer izgleda vecina je te kartice kupila za bench testove i dokazivanje a ne da bi se na njima igrala u max rezolucijama........ steta jedino kad neko sa 32+ TFT-om nasedne ne takve testove i potera crysis il neku buducu igru ima bas da poblentavi...

Posto se MS najcesce primeti pri niskom fps-u, znaci blizu 30, kako se onda npr. neke strategije tipa C&C koje imaju fpc zakucan na 30 ponasaju ?

Sta moze covek da uradi sa 2.4 TeraFLOPS, 1600 streaming shader jedinica i 2 GB GDDR5 u ovom trenutku, osim proracunavanja sveopsteg nuklearnog napada:trust:

 

[genuine]

mislis 2.4 Tera NOPS-a

@Doktor: moze svasta da se uradi. Samo treba znati kako.

Ma znam, ali toliko brzo izbacuju graficke da to nije normalno. A softver daleko kaska za njima.

SAPPHIRE Launches Special Water Cooled ATOMIC HD 4870 X2 Video Card

SAPPHIRE Technology is now introducing the SAPPHIRE ATOMIC HD 4870 X2, an exclusive new dual GPU water cooled version of the standard ATI HD 4870 X2 card. Because the article is written in Greek which is not my strongest language, I'll stick to the specs and pics, after all that's all we need. As usual, the SAPPHIRE ATOMIC HD 4870 X2 comprises of two complete HD 4870 graphics systems on a single PCI-Express card connected by an on-board PCI Express Gen 2 bridge chip. Each GPU has 1GB of GDDR5 memory, making a total of 2GB on-board memory. Core clock speed for this model is 800MHz, there are 2x800 stream processors, the memory clock speed is 1000MHz with 512-bit memory interface. What's so special in this model is the full cover liquid cooling provided by the famous OEM cooling expert Asetek. The water-block cools both GPUs, all memory chips, the bridge chip and all the power elements. Two Dual Link DVI outputs are provided as well as TV-Out. Additionally the card's bundle includes a CCL UV lamp and Sapphire USB memory stick with drivers. The card will be available starting December 18th for a MSRP of $649.
