AMD Radeon Pro WX 4100 vs Intel Iris Pro Graphics 6200 Comparison

AMD Radeon Pro WX 4100 vs Intel Iris Pro Graphics 6200

The AMD Radeon Pro WX 4100 is the decisive winner in every shared benchmark, leading by margins ranging from 170.7% to 287.2%. The Intel Iris Pro Graphics 6200, an integrated solution, cannot compete with the dedicated Radeon Pro in raw compute throughput, but its lower power envelope and integrated nature make it suitable for specific, low-power workloads.

Head-to-Head Benchmarks

The benchmark data is unequivocal: the AMD Radeon Pro WX 4100 outperforms the Intel Iris Pro Graphics 6200 in all three tests where both have scores. The largest gap appears in the Geekbench OpenCL test, where the Radeon Pro WX 4100 scores 17642 against the Intel's 4556, a delta of 287.2%. This massive lead indicates a substantial advantage in general-purpose GPU compute tasks, such as video encoding or scientific calculations.

In the Geekbench Vulkan test, the AMD card scores 18703, while the Intel solution manages 6032. This difference of 210.1% shows that the Radeon Pro WX 4100 is far better equipped for modern, cross-platform graphics APIs. The smallest relative win for AMD is in the Geekbench Metal test, but it is still a commanding 170.7% lead, with scores of 21018 for the Radeon Pro and 7764 for the Iris Pro.

The AMD Radeon Pro WX 4100 also holds all three wins in the head-to-head comparison. The data shows that the Intel Iris Pro Graphics 6200 does not win a single benchmark in this comparison. When looking at the broader picture, the AMD card's average benchmark score is 6330, placing it in the 37th percentile of all GPUs. The Intel chip's average score is 6117, putting it in the 35th percentile. While these percentiles are close, the average score for the AMD card is higher, and its closest rivals include the NVIDIA Quadro K620 with an average score of 6282 (0.8% delta) and the AMD Radeon R7 M350 with a score of 6327 (0.1% delta). The Intel Iris Pro's nearest rivals include the AMD Radeon HD 8690M (6137, -0.3%) and the NVIDIA GeForce MX230 (6077, 0.7%).

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Radeon Pro WX 4100 uses the Baffin chip based on the GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It contains 3,000 million transistors on a 123 mm² die, resulting in a transistor density of 24.4M / mm². In contrast, the Intel Iris Pro Graphics 6200 uses the Broadwell GT3e chip based on Intel's Generation 8.0 architecture, also on a 14 nm process but fabricated by Intel. The data does not list transistor count, die size, or density for the Intel part.

The core configurations differ significantly. The AMD card has 1024 shading units, 64 texture mapping units (TMUs), and 16 render output units (ROPs). The Intel integrated graphics have far fewer: 384 shading units, 48 TMUs, and only 6 ROPs. This disparity in ROPs is a key reason for the AMD card's much higher pixel rate of 19.22 GPixel/s versus the Intel's 6.600 GPixel/s. Similarly, the texture rate for AMD is 76.86 GTexel/s, while Intel's is 52.80 GTexel/s.

Clock speeds also favor the discrete card. The Radeon Pro WX 4100 has a base clock of 1125 MHz and a boost clock of 1201 MHz. The Intel Iris Pro operates at a base clock of 300 MHz and boosts to 1100 MHz. The memory subsystem is another major divider. The AMD card uses 4 GB of dedicated GDDR5 memory on a 128-bit bus, yielding a bandwidth of 96.00 GB/s. The Intel chip relies on System Shared memory, with a bus width and bandwidth listed as "System Shared" and "System Dependent" respectively. This fundamental difference means the AMD card does not contend with the system RAM for memory access.

Where Each One Wins

Based on the benchmark results, the AMD Radeon Pro WX 4100 wins in all compute and graphics scenarios where its performance is measured. Its FP32 performance is listed at 2.460 TFLOPS, with FP16 performance also at 2.460 TFLOPS (1:1). This makes it suitable for professional workloads that demand high floating-point throughput, such as CAD, 3D modeling, and video rendering. The AMD card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, covering a wide range of modern application interfaces. Its four mini-DisplayPort 1.4a outputs make it a capable multi-monitor solution.

The Intel Iris Pro Graphics 6200, with its 844.8 GFLOPS FP32 performance, is not a competitor in these heavy tasks. However, its wins are not in benchmark scores but in other areas. It has a TDP of only 15 W, compared to the AMD card's 50 W. This makes it a far more power-efficient option for basic tasks. As an integrated GPU (IGP), it requires no separate slot or power connectors, making it suitable for compact systems where space and power are at a premium. Its performance is sufficient for basic desktop usage, legacy applications, and light media playback. The data shows it supports DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0, which is a slightly older feature set than the AMD card.

Specification Differences

The most critical specification gap is in the memory and core configuration. The AMD Radeon Pro WX 4100 features 4 GB of GDDR5 memory with a 128-bit bus and 96.00 GB/s bandwidth. The Intel Iris Pro Graphics 6200 uses System Shared memory, making its bandwidth dependent on the system. The AMD card has 1024 shading units, 64 TMUs, and 16 ROPs, versus 384 shading units, 48 TMUs, and 6 ROPs on the Intel chip.

The power and physical requirements are also different. The AMD card is a single-slot solution with a 50 W TDP and a suggested PSU of 250 W, but it requires no external power connectors. It has a length of 168 mm and a height of 69 mm, and it connects via PCIe 3.0 x8. The Intel chip is an IGP with a 15 W TDP, uses a Ring Bus interface, and has no dimensions listed, as it is integrated onto the motherboard. Its display outputs are also "Motherboard Dependent," whereas the AMD card has four fixed mini-DisplayPort 1.4a outputs.

The API support differs slightly. AMD supports DirectX 12 (12_0), while Intel supports DirectX 12 (11_1). AMD offers OpenGL 4.6, and Intel offers 4.4. For Vulkan, AMD supports version 1.3, while Intel supports 1.0. The AMD card has a launch MSRP of 399 USD. Finally, while both are end-of-life products, the AMD Radeon Pro WX 4100 was released on 2016-11-09, and the Intel Iris Pro Graphics 6200 was released earlier on 2014-09-04.

The Verdict

The data is clear: for any application that relies on GPU compute or modern graphics rendering, the AMD Radeon Pro WX 4100 is the superior choice. Its performance in the Geekbench Metal, OpenCL, and Vulkan tests is consistently more than double, and in some cases nearly triple, that of the Intel Iris Pro Graphics 6200. The AMD card's dedicated 4 GB GDDR5 memory and 96.00 GB/s bandwidth eliminate the bottleneck of system-shared memory, providing a substantial advantage in texture-heavy and compute-intensive workloads. Its higher pixel rate of 19.22 GPixel/s and texture rate of 76.86 GTexel/s make it the only option for professional 3D work or serious gaming.

The Intel Iris Pro Graphics 6200 should be chosen only for scenarios where its 15 W TDP and integrated nature are more important than performance. It is a solution for basic productivity, legacy software, and systems where adding a discrete GPU is not possible or desirable. Its 35th percentile ranking and an average score of 6117 place it slightly below the AMD card's 37th percentile and 6330 average score, confirming its secondary status. If performance is the priority, the AMD Radeon Pro WX 4100 is the only choice based on this data. The Intel chip wins only on power efficiency, not on any measured performance metric.
