AMD Video Card 100-505940 AMD Radeon Pro WX 5100 8GB GDDR5 Retail

Why bougth I this video card specifically ?
Well, because GPGPU programming.
AMD has ROCm platform with HSA support on Linux.
So , the board has 8GB memory with 256 bit interface a theoretical throughput of 160 GB/s and 1792 stream processors.
Only 75 Watts maximum TDP and use a single slot.
Has a high performance per watt .
The WX 4100 model has 4GB , 128 bit bus consuming 50 Watts with 1024 cores and 96 GB/s.
Since the price of an used WX 4100 is ~252 U$ and an used WX 5100 is ~315 U$ , the best value is for a WX 5100.
The WX 7100 has 8 GB , 256 bit bus, 224 GB/s and 130 Watts , it costs 619.99 U$ and I could not find any used part here in Amazon.
I wonder 3 cards, since 24 GB in a 768 bit bus, consuming 225 Watts ,with 5376 stream processors (GCN4) and 480 GB/s are really interesting for developing software.
A Vega Frontier has 16 GB, 2048 bit bus, 4096 stream processors (GCN5) , but only 483 GB/s.
Vega Frontier has 13.1 TFlops in FP32 and the 3 WX 5100 have 11.7 TFlops in FP32.
But Vega Frontier consumes 300 Watts and 3 WX 5100 consumes 225 Watts, with 24 GB memory against 16GB from Vega Frontier.
The only point Vega Frontier has huge advantage is in half-precision , 26.2 TFLOPS.
This was the biggest mistake AMD made with Vega series. You can use half-precision in several floating point calculations you only need a number normalized between 0.000 …-0.999…, that’s why AMD claims this board is optimized to AI.
For some applications, they are right. But , for the average user, this is disaster. I don’t think Vega RX will be better.
Again, they made a mistake , unless games will be modified to use intensive FP16 um video card. This is possible, but very unlikely since there will be 2 completely diferent paths, one for AMD and other for NVIDIA. Not just some tweaks.
The total cost of 3 WX5100 was about 980 U$ and a Vega Frontier costs 956.97 U$ used.
For me, the 225 Watts , the extra 1280 stream processors , extra 8 GB of VRAM with a very similar throughput and more mature drivers made my decision in for 3 WX 5100
For professional use with CAE/CAD/CAM, Maya, Blender, CATIA,Photoshop,etc, I believe WX 7100 makes more sense.
If you are using this kind of software, perhaps a best buy could be a Quadro P2000.
For my problem , a P2000 has only 5 GB , 160 bit bus , 140 GB/s and 1024 CUDA cores( a CUDA core is not directly comparable to GCN 4 stream processor, but GCN 4 has improved real use case performance per core).
For the normal user, who needs things like color calibration, speed in render, driver reliabiliity and performance , in general, I found most reviews favored NVIDIA Quadro P2000 .
AMD is creating an open source environment for improving software support, which is ( and always was, even when AMD Radeon was called ATI Radeon) the worst .
The hardware is really good, but NVIDIA delivered the best software support for it’s Quadro series ( and NVIDIA made huge mistakes sometimes).
So, for my purpose, which is not the common use for this card, it is the best.
In fact, 3 of it.
For me, is a good bargain, for others, could be a mistake.
I think you must analyze the cost
