شاید نتونیم کاملا تخصصی صحبت کنیم اما میشه مقایستاتی رو در این مورد انجام داد .
خوب این جواب یکی از متخصصین سایت bit-tech به یکی از یوزرها در همین مورد تفاوت استریم ها هست .
The stream processors in Nvidia's and AMD's respective architectures are slightly different, but there's a reason for that. Nvidia's architecture is scalar, while AMD's architecture is superscalar. Basically, with Nvidia's architecture, you can throw any piece of code at it and it will run on as many of the stream processors as it needs - they all have the same functionality (bar the special function unit - there's one of those per eight stream processors but it's not part of the count) and are pretty generalised. It's a brute force method, although Nvidia would crucify me for saying that - you just throw code at it and it works everything out itself.
On the other hand, AMD's architecture has blocks of five (well, technically six) stream processors that have differing functionality. Four of them can handle FP MAD, FP MUL, FP/INT ADD and dot product calculations), while the fifth unit can't handle dot products, INT ADD or double precision calculations, but can handle INT MUL, INT DIV, bit shifting and transcendental calculations (SIN, COS, LOG, etc). It's a bit more complex, but if the code is optimised well, it can deliver much higher performance - that's why the FLOPS throughputs on the AMD chips are quite a bit higher, too, because they only take FP MAD and FP MUL into account and all of the units in the AMD chips can do those calculations (they're the most widely used).
I'd say the AMD architecture is a lot cleverer in many respects, but it does require a bit more work from the developer to achieve peak performance.
فکر کنم خوندنش آسون باشه .

... البته تقریبا .... این یارو تو فضا سیر می کنه بابا می خواد انویدیا رو بدبخت کنه تا اون موقع هم که بخوان 300 رو عرضه کنن احتمالا ATI سری 6000 هم معرفی می کنه !
تو جعبه کارته هم یدونه Mass Effect 2 اورجینال باشه، خیلی هم دراز نباشه از 6 اینچ بیشتر نباشه، کولینگشم خفن باشه با فن گنده دوبل بی‌صدا، البته روشم عکس Guts باشه امتیاز مثبت حساب میشه، هیچی دیگه هم حالیم نیست فقط همینو میخوام
