AMD Radeon HD 7870 (GHz Edition) vs AMD Radeon Pro WX 3100

The AMD Radeon Pro WX 3100 is an end-of-life workstation graphics card that released in Q2 2017 with a MSRP of $199. It is built on the GCN 4.0 GPU microarchitecture (codename Lexa) and is manufactured on a 14 nm process.

Memory

The Pro WX 3100 has 4 GB of GDDR5 memory, with a 1,500 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 96 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The Pro WX 3100 includes 512 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 925 MHz and can dynamically boost its clock speed up to 1,219 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The Pro WX 3100 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DisplayPort 1.4a, mini-DisplayPort 1.4a display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 65 W.

Benchmark Performance & Value

The Pro WX 3100 has the 278th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 3.53% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 3,690.5 score and $199 launch price (MSRP) gives it a performance per dollar of 18.55. This is the 89th best in value for the 3DMark 11 Performance GPU benchmark.
