AMD Radeon 740M vs AMD Radeon Pro WX 3200 Comparison

AMD Radeon 740M and AMD Radeon Pro WX 3200 address very different segments of the graphics market. The 740M is a modern integrated graphics processor (IGP) from the Phoenix2 chip, built on the RDNA 3.0 architecture. The Pro WX 3200 is a dedicated, single-slot workstation card from the older GCN 4.0 era. The data shows a clear split: the newer IGP offers superior raw compute potential, while the older discrete card holds the edge in the one benchmark where both were recorded.

Where Each One Wins

The Radeon 740M is a mobile-first IGP designed for thin-and-light laptops. Its win condition is architectural modernity and raw throughput. With 256 shading units, 16 texture mapping units (TMUs), and 8 render output units (ROPs), it is built for efficiency. The chip operates on a 4 nm process from TSMC, which allows it to pack 20,900 million transistors into a 137 mm² die. This density is the key to its performance. The FP32 compute rate of 2.867 TFLOPS is the highest in this comparison, and the RDNA 3.0 architecture brings features like 4 ray tracing cores and support for DirectX 12 Ultimate (12_2). This makes it the better choice for modern gaming workloads and compute tasks that leverage newer API features. The Vulkan score of 15568 further reinforces its strength in cross-platform graphics.

The Radeon Pro WX 3200 is a workstation card, and its win condition is dedicated memory and driver stability in a professional context. It comes with 4 GB of GDDR5 memory on a 128-bit bus, providing 96.00 GB/s of bandwidth. This is a finite, dedicated pool that does not compete with system RAM for capacity. The card uses 640 shading units, 32 TMUs, and 16 ROPs, which is a higher raw unit count than the 740M. It also has a higher TDP of 65 W, reflecting its discrete nature. In the OpenCL benchmark, it scored 11228, beating the 740M by 9.4%. This suggests that for compute tasks that rely on memory bandwidth and the older, well-optimized GCN instruction set, the Pro WX 3200 can still hold its own.

Architecture Differences

The architectural gap between these two GPUs is significant. The 740M uses the RDNA 3.0 architecture, while the Pro WX 3200 uses GCN 4.0. This is a generational leap. RDNA 3.0 is designed for high efficiency and scalability, with a focus on gaming performance per watt. The 740M is fabricated on a 4 nm process at TSMC, which is a major advantage over the 14 nm process used for the Pro WX 3200, which was made by GlobalFoundries. This process difference is why the 740M can achieve a transistor density of 152.6 million per mm², compared to the Pro WX 3200's 21.4 million per mm².

The 740M is an IGP, meaning it shares system memory via the PCIe 4.0 x8 interface. Its memory bandwidth is labeled "System Dependent," which makes its performance variable based on the host laptop's RAM. The Pro WX 3200, by contrast, is a discrete card with its own 4 GB of GDDR5 memory and a fixed 96.00 GB/s bandwidth. The Pro WX 3200 uses a PCIe 3.0 x8 interface. The 740M also includes 4 ray tracing cores, a feature entirely absent from the Pro WX 3200. The 740M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro WX 3200 is limited to DirectX 12 (12_0) and Vulkan 1.3. The Pro WX 3200 has a dedicated display output array of 4x mini-DisplayPort 1.4a, whereas the 740M's outputs are defined by the motherboard.

Head-to-Head Benchmarks

The only direct benchmark recorded for both GPUs is the Geekbench OpenCL test. In this test, the AMD Radeon Pro WX 3200 scored 11228, while the AMD Radeon 740M scored 10172. The winner is the Radeon Pro WX 3200, with a delta of -9.4% for the 740M. This is a notable result for the older card. The Pro WX 3200's dedicated memory and higher shading unit count (640 vs 256) likely contribute to this lead in a memory-sensitive compute workload.

The 740M, however, has a separate Geekbench Vulkan score of 15568, which is not recorded for the Pro WX 3200. This score is significantly higher than the 740M's own OpenCL score, indicating that the RDNA 3.0 architecture is particularly strong in modern, low-overhead APIs. The 740M's FP32 compute rate of 2.867 TFLOPS is 73% higher than the Pro WX 3200's 1.658 TFLOPS. This raw compute advantage is not fully reflected in the OpenCL benchmark, but it suggests the 740M has more theoretical headroom. The 740M also has a higher pixel rate (22.40 GPixel/s) and texture rate (44.80 GTexel/s) compared to the Pro WX 3200 (20.72 GPixel/s and 41.44 GTexel/s).
