这就是GPU的明天么？

However we did decide to measure the processing time to see if there was any advantage to using CUDA even with our crude implementation, or on the other hand if was going to take long, exhaustive practice to get any real control over the use of the GPU. The test machine was our development box – a laptop computer with a Core 2 Duo T5450 and a GeForce 8600M GT, operating under Vista. It’s far from being a supercomputer, but the results are interesting since our test is not all that favorable to the GPU. It’s fine for Nvidia to show us huge accelerations on systems equipped with monster GPUs and enormous bandwidth, but in practice many of the 70 million CUDA GPUs existing on current PCs are much less powerful, and so our test is quite germane.
The results we got are as follows for processing a 2048x2048 image:

CPU 1 thread: 1419 ms

CPU 2 threads: 749 ms

CPU 4 threads: 593 ms

GPU (8600M GT) blocks of 256 pixels: 109 ms
GPU (8600M GT) blocks of 128 pixels: 94 ms
GPU (8800GTX) blocks of 128 pixels / 256 pixels: 31 ms

....
The second notable observation is that even the slowest GPU implementation was nearly six times faster than the best-performing CPU version.

某厂和某厂的粉丝们还在为自己终于超越了对手2年前的科技而兴高采烈的时候，却没发现某长的一只脚已经跨进了另一个领域。
一等品GT200都拿去做Tesla了，二等品才拿来做成GTX280卖，残次品做260。

不管。。降价就好。。。。。。。。。。。。。。。。。

yeemartin!

某些Q又开始诋毁某厂。

识得捡你才是老板！！

貌似,这和CPU的策略是一样的嘛
某社不就在N年前就把残次品屏蔽部分残次部分,然后标上X羊卖么

本来不想说的，实在忍不住了..

“既然nV已经1只脚跨入1个很有前途的领域，干脆另1只脚也跨进去吧！gpu领域就留给amd去跟intel抢汤喝。”

哈哈 有理{happy:]{happy:]{happy:]

NV将和AMD联合攻I，取名NMD

如果一等品做GTX280估计现在情况就不一样了。

拿高級的GT200去跑GeForce會虧更多。XD
輸了面子也得贏了裡子，那晶片那麼大一顆....
