Hello,
sorry to be late with this and sorry it is so ugly.
I did some test with two adapters I have, PEX8111 and PEX8112.
The scope was to see if it was possible to use good gpus on motherboards without AGP slots, so even in that case and without spending a lot would be possible to have good playback capabilities and some gaming from early/mid 2000.
The motherboard is a Supermicro 370DLE with two LIN-LIN and a pair of P-IIIS 1400.
I assume mem speed would not be stellar because of registered ram (2GB) and because of the chipset not exactly built for speed, and this could hit performance. OS is XP SP3
The tests where Final Reality Bus speed (easy and fast) and 3DMark01
the cards:
- GF5200 PCI as a control, drivers 67.77
- HD 5450 DDR3 PCIe Catalyst 14.4
- GT 730 PCIe x1 64bit Kepler drivers 381. something... The last one for XP
- GTX 450 profile, the only one with external power, to avoid power shortage of PCIX bus. Drivers same as above
the PCI bus speed is 66Mhz.
it is very easy to see how 8112 is far better then 8111, the results are next to each other.
For FR it’s in mb/s , for 3dMark you have multiply x100.
It was the only way to fit all.
The best card for 3DMark was the GTX450 with 9666 points.
As a reference, the FX5200 (66Mhz bus) achieved 5075
I doubt the doubling of tualatins had any impact, I think it would be the same for 1 CPU.
And yes, 2D bus speed for FX5200 is stellar, do not know why, I did the tests several times. Maybe because the FX series had a dedicated 2D unit that better interacts with the benchmark. Do not know.
Of course all cards except the fx5200 give perfect FullHD playback with very low cpu usage (around 10% in the worst case).
