HIS Radeon HD 3850 IceQ 3 TurboX VS. EVGA GeForce 8800 GT

i would say the 8800gt over the 3850 hands down

but that 8800gts you listed? hell no, you can get a 4870/gtx260 for that money

the 8800GT is much faster than the 3850. but i would suggest you get a 4850 or 4870 instead.

I want to know why is it much faster if the 3850 has faster clock, please I really want to know why? I don't want to be ignorant.

8800GT GTS dont worth the extra.

because the shader runs at a much higher speed and the architecture of the nvidia card is better.

Do you know what is the Shader clock speed of the 3850??

8800gt i believe runs 20-25% faster.

clock speeds aren't a good way to compare cards. my old 7600GT runs at 580Mhz, but can't even hold a candle to to the 8800GT. it depends on many factors, which depend on the manufacturer. the only way to compare is through real world benchmarks. even artificial benchmarks arent so great for comparing performance. the 2900XT was great in synthetics, but was terrible in games.

there is only 1 speed for the GPU.so both core and shader run at the same speed.

i would have to say the gt, dx10 cards have shaders the 3850 has a fixed shader/core but the gt,s shaders run a lot faster than the core

hope this helps

As others have said, clock speed isn't the only factor. Here's an analogy:

You are taking a road trip and there are two highways you can take. One has a speed limit of 65 mph, the other is 55 mph. You take the 65 mph highway (since 65 is faster than 55), and find that the road loops and turns and has stop signs and traffic. Your trip takes 2 hours. On the way back you try the 55 mph road and find that it's an empty, straight road to your destination and only takes 1 hour, despite having a slower speed limit.


I'm not a GPU engineer so I can't really go into detail about why a card can perform better with a slower clock speed, I just know that it can =)
Things like shader clocks and architecture and other complicated things all come into play.

Now, if you're comparing two cards of the same type (say, two 8800 GT cards) then yeah clock speed will be the determinant, as every other factor between the two cards will be the same since they're both of the 8800 GT variant.

why not choose the HD4870?

faster and cheaper than 8800GTS you got

Here's a couple of articles that will help explain some things

If you're on a hard budget, then the 8800GT will beat the 3850 at $110
if you have budget room, then go with a HD4850 at $140- $150

Kind of wonder how the 38xx series would have performed if they had equal number comparative SP's to the 8800GT's 112. ie.. 640 instead of 320, (320/5=64 nv SP's). They may have had slower shaders but a huge number more and with the faster clocks would that have leveled the playing field or not at all? Can't say that would have made a difference when enabling AA/AF but still.
