I really don't care what the numbers themselves mean individually. I'm only using them to COMPARE one card to the other in terms of how much processing power is available VS each other. You know GPU MHz speeds aren't a good comparison. I mean, just look at Haswell CPUs versus Sandy Bridge CPUs. Clock-for-clock, the Haswell does a hell of a lot more at the exact same clock speed.
Hmmmm. Love to see how all my cards compare in terms of Pixels/sec fill-rate.
MOps/s is Million Operations per second. MPix/s is Million Pixels per second. I notice by the time we get to the GTX 2xx series and higher, they stop reporting MOps and start using FLOPS - probably a much better way to compare GPU horsepower than straight instructions.
ATI Rage IIc - 60 MOps/s - 60 MPix/s
TNT2 - 250 MOps/s - 250 MPix/s (4.17x increase over the Rage IIc)
Radeon 7500 - 580 MOps/s - 580 MPix/s (2.32x the TNT2)
Radeon 9550 - 1,000 MOps/s - 1,000 MPix/s (1.72x the 7500)
Radeon X800 Pro - 5,700 MOps/s - 7,600 MPix/s (looking at on E-bay, 7.6x increase over the 9550)
Geforce 6800 Ultra - 6,400 MOps/s - 6,400 MPix/s (0.84x increase, actually less than x800 - slight increase in MOps)
GeForce 7800 GTX - 10,320 MOps/s - 6,880 MPix/s (0.9x the x800 Pro, still less, but about double the Ops/s)
GeForce GTX 480 - 1,344.96 GFLOPS - 33.60 GPix/s (4.9x the 7800GTX - crazy powerful)
GeForce GTX 980ti - 5,632 GFLOPS - 96 GPix/s (2.86x the GTX 480 - now it's getting ridiculous)
I threw in the 6800 Ultra because 1. I had it in my laptop first and 2. it's very close to the X800 so I can compare between nVidia and ATI for its time. The 6800 Ultra had Shader 3.0, as you guys pointed out, so it's a better graphics card I think. I mean, there's a reason that after I got the 7800 GTX replacement in my laptop, I've used nothing but nVidia since - but I wonder. I've been reading lately about some dirty shut-out practices by nVidia on game developers. Let me see if I can put the YouTube video about it... https://www.youtube.com/watch?v=ZcF36_qMd8M
That video made me want to get an AMD card for the next system I build for a friend....that and the new Ryzen intrigues me.
Take a look at that X800 Pro I linked above - it looks dirty and I've sent a question to the seller asking if that's dust/dirt or corrosion. He claimed on the listing that it works. If it's dirt, I can clean it thoroughly with alcohol and a toothbrush, but if it's corrosion, I'd rather not waste my money. But THAT listing would let me get this card AND the Barton CPU for roughly $30, a pretty sweet price point. Then I can test everything. It would drastically increase the gaming performance of this system even with the AGP 4x limitation, without actually stepping all on my Dell XPS laptop (7800GTX). This might actually be the one, I'm thinking... if it works. And as a bonus, the X800 should run Doom 3 at Medium or High fairly well (I don't care about going over 60FPS - it is a retro system after all)
And another thought - when I picked up my box copies of Half-Life 2...NOWHERE on the box does it say STEAM, but I'm pretty sure there's no such thing as HL2 without Steam...so weird. Any thoughts on that too?
