GTX 280 Texture fill rate faster then GTX 285?

[Zerk]

Hello tech buddies!

I'm wondering why the Texture fill rate on the GTX 280 is Faster then it is on the GTX 285.

GTX 280 - 48.2GTexel/s
GTX 285 - 47.4GTexel/s

Why?

Everything else is faster.

Sorry such a short Question.

Thank you !

I checked Right here at Nvidia.

http://www.nvidia.com/object/product_geforce_gtx_285_us.html

It shows Texture Fill Rate should be 51.8GTexel/s

Why does my GPU-Z not show 51.8GTexel/s but show 47.4GTexel/s

Looking up 20 diff GPU-Z GTX 285's I found mine must be right.

So why Does Nvidia Say it's 51.8GTexel/s if its Not!

Its 47.4GTexel/s For real!

Well, did you consider that it probably down clocks itself while idle? If it's downclocked then GPU-Z will report a lower fill number than it would be under load.

 

[Zerk]

Yup.

Still the same.

I'll try again though.

OK,I tried again,Same thing.

 

[Zerk]

Anyone?

I still do not see why this is right?

its 46Mhz Faster,159GB/s Memory!

So what exactly is a GTexel? and why is it slower? on the GTX 285,if it's actually faster.

Anyone here more knowledgeable on this than me?

Thank you!

Whats the difference, if any, between what nVidia has for core clock speed and what you have for core clock speed, and the speed of the memory on each?

 

[cjl]

What are your core and shader clocks, and what are the reference core and shader clocks?

 

[JAYDEEJOHN]

@OP, were giving you hints

All 3 of my gtx 285's show the correct fillrate.

 

[Zerk]

Witch are what chef7734?

Core=648
Shader=1476
Mem=1242


Nvidia Say's GTX285 = 51.8GTexel/s

Mine says GTX285 = 47.4GTexel/s

 

[Zerk]

Forgot.

Thank you!

Well it would be
gpu 690
mem1300
shader 1552
51.8 texture fill rate
