Number crunching :
AMD Radeon Pro WX 4100 / WX5100
Posted 7 Feb 2017 by TheHoosh
Hi fellow crunchers,
I am currently considering buying a new GPU to replace my Geforce 750TI.
One of my key requirements is a low TDP (< 80W) since electricity is pretty expensive where I live and my machine runs 24/7.
After some research, I came across the following two AMD cards:
AMD Radeon Pro WX 4100
AMD Radeon Pro WX 5100
When compared to my Geforce 750 TI (from Palit), the stats look like this:
750 TI: 1600 GFLOPS (SP), 50 GFLOPS (DP), 60W TDP
WX 4100: 2000 GFLOPS (SP), 125 FLOPS (DP), 50W TDP
WX 5100: 4000 GFLOPS (SP), 250 GFLOPS (DP), 75W TDP
Obviously, the WX 5100 delivers the most computational power, especially 5 times more DP, which should be pretty important for MW.
But even the 4100 would deliver twice as much DP performance as my 750TI while using less electricity at the same time.
Since those are "professional" cards, they cost twice as much as "ordinary" AMD 460 / AMD 470 cards. However, their TDP is significantly lower:
120W (AMD 470) vs. 75W (WX 5100) abd 75W (AMD 460) vs. 50W (WX4100).
Thus, after less than 1.5 years of crunching, the higher price has already armortized at 27 (€)-cents per KWh
Is anyone crunching MW on a 4100 or 5100 and could tell me about their experiences regarding energy consumption, heating, etc.?
