[VR-Zone] AMD Radeon HD 7970 specifications slide leaked - Page 2

post #11 of 68
I know this has been asked time and time before, but what's the big deal with ROPs in AMD and Nvidia cards? Nvidia= more rops/less shaders, AMD= more shaders/less rops. I understand that AMDs texture fill rate is better, but worse raw fill rate. What difference does this make vs. Nvidia?

OT: Might just wait for 600 series seeing how things are going atm...

Well I wonder how will it perform clock for clock against the 6970. It's starting at 45mhz advantage which isn't very much. If we set them the same I wonder how it will perform.

TDP is rated under 300W :s

ROPs make a lot of difference. Looks @ 5830. even with 1120SP it was nut much difference then HD 4890 with 800SP because both had 16 ROPs. HD 5850 in the other had with 32 ROPs was much much faster.
800SP + 320SP = HD 5830
1120 + 320SP = HD 5850
The difference from HD 5830 and HD 4890 was 5% at best
The difference from HD 5860 and HD 5850 was at least 20%.

Clock speed says nothing of performance between 2 different architectures, so why bring it up. Also, 6970 base clock is 825 mhz.

300W TDP? If that's real, this card is going to be the new GTX 480

No, 6970 base clock is 880 MHz

This is sounding more and more fake by the second. Previous leaks indicated a 230W tdp, now this rumored leak says "less than 300". What?
3W at idle? Yeah right smile.gif I don't see 3W idle at all.

fake. no way a 28nm AMD is pulling 300w

However doesn't this seem to confirm the need for 8+6 pin?

I think it's just a little insane for a ~400 mm² chip to draw that much power. On a MUCH lower power process too.
