The MRSP of $499 is also very attractive.
What? Of course, even the GTX 280 does that in virtually every benchmark. The 295 beats the 4870X2 in most tests, and it's priced at a very similar level.
The Radeon HD 4870 X2 is a unique video card because it takes two of AMDâ€™s highest-end GPUs and puts them on a single board, with all the glory of their fastest GDDR5 memory. NVIDIA didnâ€™t do that here; much like the 9800 GX2. NVIDIA instead used the memory subsystem of the GTX 260. The GTX 260 has 128MB less RAM and a more narrow memory bus than the GTX 280. This is its weakness at high settings and our game testing has proven that. We are still not going to rule out the possibility of immature drivers for this card, but our gut tells us otherwise and time will surely confirm or deny our thoughts on this.
Fallout 3 performs faster on the Radeon HD 4870 X2 at 2560x1600 with 8X AA and the highest in-game settings. Crysis: Warhead performs faster on the Radeon HD 4870 X2 at 1920x1200 with 8X AA. See a pattern? When you really start to crank up the settings, a high resolution plus a high AA setting like 8X AA, the 4870 X2 is pulling ahead. This shows some kind of possible memory bottleneck with the GTX 295.
[H] thinks the same thing about higher AA levels.
Until Nvidia chooses
to prioritize the dual GPU card and not just fab it for mythical "Crown" status, they will have the inferior dual GPU solution.
The difference is ATI has chosen this tech, Nvidia's offering is always an OMG we gotta get the "Crown" back reaction.
I have no doubt that Nvidia could produce a phenomonal dual gpu card, if they so choose.
But they would have to change pretty much their whole GPU vision.
1 power connector per pcb, why do single pcb GT200's use 2?
