Small comparison on full compute performance (Anima) of 5090 (600,475 and 400W) vs 6000 PRO MaxQ (325W), and 6000 PRO WS/SE (600W).

Hello guys, hoping you're doing fine!

After selling some cards, I got a 6000 PRO MaxQ, which it's power limit range from 250W to 325W.

I still have a 5090, which it's power limit range ranges from 400W to 600W.

Since I had these, and I like to do compute for diffusion (txt2img, txt2video, img2img, etc), I wanted to compare them.

I also rented on runpod, a 6000 PRO WS edition, which it's power limit ranges from 150W to 600W (yes, lower than the MaxQ)

Important note: I did undervolt+overclock the 5090 and the 6000 PRO MaxQ. I can't modify the clocks or power on the rented GPUs on runpod.

So for this test, I ran these settings for the software:

I ran these settings for the samplers and steps:

Sampler Settings

On text:

  • EXP Heun 2 x0 SDE for first 25 steps
  • ER SDE for 10 hires pass steps
  • Upscale by 1.5x
  • 896x1088 resolution
  • Batch size 4
  • CFG 5
  • Shift 3
  • Denoise Strength: 0.2
  • Upscaler: NVIDIA Ultra

For the hardware, I ran them headless, (with LACT):

  • RTX 5090:
    • 2930Mhz max core clock
    • 1000Mhz core clock offset
    • +4400Mhz on VRAM (total 16000Mhz)
    • 400, 475 and 600W
  • RTX 6000 PRO MaxQ:
    • 550 core clock offset
    • No max core clock
    • +5270Mhz on VRAM (total 16000Mhz)
    • 325W
  • RTX 6000 PRO WS:
    • Stock
    • 600W

With all this data, I have these results:

GPUPowerNotesTimeVS Baseline
RTX 5090600WBaseline36s-
RTX 6000 PRO SE/WS600WNo tuning39s-8.3%
RTX 5090475WUV+OC42s-16.7%
RTX 6000 PRO MaxQ325WOC48s-33.3%
RTX 5090400WUV+OC48s-33.3%

Or also, using the 5090 at 400W as baseline:

RTX 5090475WUV+OC42s+12.5%
RTX 6000 PRO WS/SE600WNo tuning39s+18.8%
RTX 5090600WUV+OC36s+25.0%

While running this task, the cards hovered around these core clocks:

  • 5090 600W: ~2500Mhz core clock
  • 5090 475W: ~2100Mhz core clock
  • 6000 PRO WS/SE 600W: ~2200Mhz core clock
  • 5090 400W: ~1800Mhz core clock
  • 6000 PRO MaxQ: 1400-1500Mhz core clock.

So, as you can see, the 5090 is 25% faster than the 6000 MaxQ here but by using 84% more power.

At the same time, the 6000 PRO WS/SE, untuned is 18.8% faster and also using 84% more power. In theory though, if you undervolt + overclock the WS/SE, it would be faster than the 5090.

And lastly, the 6000 PRO MaxQ performs the same as 5090 while using 75% of the power, which is quite impressive for how much power limited it is.

If anyone with a tuned 6000 PRO/WS can do the test, let me know!

With all this data, I have these results:
