7900Gt 3dmark scores

[t024484]

the scores were this:

7900GT SLI -- 3dmark 2003 >>>23340 all default @CPU 1800Mhz /VGA default


7900GT --3dmark 2005 >>> 8580 (only get single 7900 score maybe drivers issue) all default @CPU a 1800Mhz //VGA default


7900GT --3dmark 2006 >> 4635 (only get single 7900 score maybe drivers issue) all default @CPU a 1800MHZ //VGA default

There is quite an easy way to compare graphic cards independently from the system that you are using, using the following calculation:
(Mem BW*Fill Rate*Vertices/sec)exp1/3 where all three parameters are expressed in 10exp9

The standard 7800GT (400/1000) will give you
(32.0*8.8*0.7)exp1/3 = 5.8

The 7800GTX (430/1200) gives
(38.4*11.3*0.86)exp1/3 = 7.2

The 7800GTX512 (550/1700)
(54.4*13.4*1.1)exp1/3 = 9.3

The 7900GT (450/1320)
(42.2*10.8*.9)exp1/3 = 7.5

The 7900GTX (650/1600)
(51.2*15.6*1.3)exp1/3 = 10.1

The 7900GT and 7900GTX figures are just based upon the info from Mascaras.
If these are correct, the conclusion is that the 7900GT is 4% faster as the basic 7800GTX and that the 7900GTX is 40% faster as the basic 7800GTX and 9% faster as the 7800GTX512.

yep, the info that i read in few sites is that 7900GTX is faster 8%-10% than 7800GTX 512Mb so you are correct:

G71, 7900 GTX is eight to ten per cent faster
Than 7800 GTX 512

:
ASIAN partners are disappointed with the upcoming Geforce 7900 GTX cards. Most of the companies already have the samples and tested them but they are not happy with the performance. First tests indicate that in the best case scenario, Geforce 7900 GTX cards are eight to ten per cent faster than the last and rarely available Geforce 7800 GTX 512 card.

This means that 7900 GTX might get close to ATI's X1900 XTX card but it will lose in many of the benchmarks. We suspect that at 4X FSAA and eight or sixteen times Anisotropic filtering ATI X1900 XTX can still keep its crown, but we still have to see this. Asian partners placed limited quantities order for G71, 7900 GTX chips and they ordered less chips then they usually do, according to sources.

When Nvidia launched its flagship 7800 GTX 512 a true performance leader, the partners ordered thousands of chips and got a handful of them, while now even you can get thousands of chips, no one wants to risk buying a few thousands of them. However, we still think that Geforce 7900 GTX if priced aggressively have a chance to be a good seller as people like the Clan of McNvidia.

Sample 7900 GTX at 650MHz core should be distributed now as the launch day the 9th of March is getting closer. We know that Nvidia won't have any shortages of those chips as, for goodness sake, this chip will find its place in Sony Playstation 3 but at modest clocks. Sony literally wants millions of chips.

In "best case scenario"

would be funny if they actualy sell very well but the stores run out fo stock cause the partners themselves only bought low quantities of the cards and dont have enough cards to supply cause they screwed up
