ATI R520 & ATI SLI

Here's a couple of snippets from TechPowerUp regarding ATI's latest Hardware! First up is some interesting info on ATi's R520 GPU.
We have confirmed the 24 pipelines rumors from several independant sources. However, these 24 pipelines are not comparable to 24 of today's pipelines - multiply by 1.3. So the 24 pipelines will have the performance of 32 "normal" pipelines. The result of this is that the R520 will be two times as fast as the currently fastest X850s.
Next up is info on ATi's SLI
While NVIDIA SLI splits the screen into two parts and one GPU renders each half, ATI's solution breaks the screen into little squares. Remember the chessboard effect you had when pipelines were bad with the softmod?
For More Info Warp2 .... TechPowerUp

... and they'll cost $1500? They need to work on price, not performance. |

wow, two times the power of a X850... theoretically. Funny though that no one mention the fact that the R520 is no longer an efficient FP24 GPU but a more power-intensive FP32 GPU much like GF FX and GF 6800 now have been for years. FP32 precision eats performance and it won't make any exception with the R520 chip. |

perhaps they took that into consideration. double the speed of the previous generation.. that would fit wigh how the graphics development has gone so far. |

"Funny though that no one mention the fact that the R520 is no longer an efficient FP24 GPU but a more power-intensive FP32 GPU much like GF FX and GF 6800 now have been for years." Somewhat contradictory statement seeing as how the R300 series "efficiency" allowed it to kick the snot out of the FX cards and the "efficiency" of the R400 series allowed it to continue to compete with the more "power-intensive" 6800 series. I guess you have forgotten that the "power-intensive FP32 gpu" known as the FX series was an abysmal failure in terms of efficiency and performance. The fact that ATI has been able to still compete on a level play field with nV using a 3 year old marchitecture is more of a compliment to ATI than anything nVidia has accomplished. In order for ATI to increse their performance and capabilities, they had to increase the power requirements of R520. Show me any new CPU/GPU generation that has not had to do such for performance improvements? For you to try to point out such a "failure for ATI" and a "triumph for nV" appears to have backfired. |

I think you didn't understand a single word of what I said before. I don't even know where to respond to your post since you seem to have completely misinterpreted my post. I have said nothing negative about ATI nor positive about nvidia for that matter. I'm just wondering why some people think that doubling the pipelines will also double the performance of the card although the work required to do the same calculations increases because of the precision which is higher than before. This has nothing to do with increasing power, I was solely talking about the increase workload which needs to be done to get FP32 precision because FP24 precision is no more with the R520. |
