AMD Radeon R8 M445DX vs Intel Iris Pro Graphics 5200 Comparison

AMD Radeon R8 M445DX and Intel Iris Pro Graphics 5200 are both end-of-life integrated-class graphics solutions, but the data reveals a clear performance hierarchy despite their similar market positioning. In the only head-to-head benchmark available, Geekbench OpenCL, the Intel Iris Pro Graphics 5200 scores 5042 against the AMD Radeon R8 M445DX’s 4727, a 6.2% advantage. This single decisive result, combined with each GPU’s broader benchmark profile, paints a nuanced picture where architectural choices and feature support matter more than raw compute alone.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the sole direct comparison, and it favors Intel. The Iris Pro Graphics 5200’s score of 5042 is 6.2% higher than the Radeon R8 M445DX’s 4727, a margin that, while not overwhelming, is consistent across the two GPUs’ overall standings. The Intel part sits at the 26th percentile among all GPUs, while the AMD part sits just one percentile higher at 27th, yet the Intel chip’s average benchmark score of 4360 is notably lower than its OpenCL peak — a gap explained by its additional Vulkan score of 3677, which drags down the average. The AMD part’s average benchmark score is 4727, equal to its OpenCL result, indicating a more consistent single-API performance profile.

Looking at nearest rivals reinforces the closeness of these two parts. The Radeon R8 M445DX’s closest competitor is the AMD Radeon R5 M335, which scores 4752 — a mere 0.5% difference. The NVIDIA Quadro P400 trails by 0.9%, and the AMD Radeon R5 M255 leads by 1.3%. Interestingly, the NVIDIA GeForce RTX 3080 12 GB appears in the rival list with a score of 4791, just 1.3% ahead — a reminder that OpenCL workloads can compress performance gaps across vastly different hardware tiers. For the Iris Pro 5200, its nearest rival is the NVIDIA GeForce RTX 4070 GDDR6 at 4335, a 0.6% deficit, while the NVIDIA GeForce 930M is 0.6% ahead and the GT 645M is 1.2% ahead. The AMD FirePro W2100 trails by 1.5%.

The compute fundamentals explain part of the OpenCL delta. The Intel part delivers 736.0 GFLOPS of FP32 performance, while the AMD part delivers 653.4 GFLOPS — an 11.2% gap in raw shader throughput. However, the AMD part achieves this with a higher boost clock of 1021 MHz versus Intel’s 1150 MHz boost, and both have 320 shading units. The texture rate tells a different story: Intel’s 40 TMUs produce 46.00 GTexel/s, more than double the AMD part’s 20.42 GTexel/s from 20 TMUs. Yet the AMD part wins in pixel throughput, with 8.168 GPixel/s from 8 ROPs versus Intel’s 4.600 GPixel/s from 4 ROPs. This suggests the Intel GPU is better suited to texture-bound workloads, while the AMD GPU handles fill-rate-bound scenes more efficiently.

The Verdict

The data unequivocally favors the Intel Iris Pro Graphics 5200 in the only direct benchmark. Its 6.2% OpenCL lead is backed by a higher FP32 throughput (736.0 vs 653.4 GFLOPS) and a dramatically higher texture rate (46.00 vs 20.42 GTexel/s). For anyone choosing between these two for general-purpose compute or OpenCL-accelerated tasks, the Intel part is the pick. The AMD Radeon R8 M445DX does offer one counterargument: its pixel rate of 8.168 GPixel/s is 77.6% higher than Intel’s 4.600 GPixel/s, which could matter in specific rendering scenarios. However, with zero benchmark wins for the AMD part and one for Intel, the overall verdict is not close.

The percentile data reinforces this. Both GPUs are near the bottom of the performance distribution — 27th and 26th percentiles respectively — but Intel’s higher average score of 4360 versus AMD’s 4727 is misleading because of the Intel part’s Vulkan result. The OpenCL score is the more reliable indicator for compute, and there Intel wins decisively. The Intel part also has a defined TDP of 45 W, while the AMD part has no listed TDP, suggesting the Intel solution is a known quantity for system integrators. Neither part has a launch MSRP listed, so price is not a differentiating factor per the available data.

Where Each One Wins

The Intel Iris Pro Graphics 5200 wins in every benchmark category where a direct comparison exists. Its OpenCL score of 5042 is the single highest benchmark result in this matchup. The architecture supports a broader feature set for its time: it lists DirectX 12 (11_1), which is functionally similar to AMD’s DirectX 12 (12_0) but with a lower feature level. Intel also offers Vulkan 1.0, whereas AMD offers Vulkan 1.2.170 — a newer version. However, Intel’s generation 7.5 architecture, built on a 22 nm Intel process, delivers higher clock speeds (1150 MHz boost) and more TMUs (40 vs 20), which explains its texture rate dominance.

The AMD Radeon R8 M445DX, despite losing the benchmark, has clear structural advantages. Its GCN 3.0 architecture on a 28 nm TSMC process includes 1,550 million transistors on a 125 mm² die, a transistor density of 12.4M per mm². It offers a higher pixel rate (8.168 GPixel/s) and a more modern API set, including OpenGL 4.6 and the aforementioned Vulkan 1.2.170. The AMD part’s base clock of 780 MHz is higher than Intel’s 200 MHz base, though the boost clocks are closer (1021 MHz vs 1150 MHz). For systems where the CPU-integrated GPU is paired with the display, the AMD part’s higher ROP count (8 vs 4) could provide better performance at lower resolutions in fill-rate-bound scenarios.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The AMD Radeon R8 M445DX uses the GCN 3.0 architecture on a 28 nm TSMC process, while the Intel Iris Pro Graphics 5200 uses Intel’s Generation 7.5 architecture on a 22 nm Intel process. The AMD part integrates 1,550 million transistors into a 125 mm² die — a density of 12.4 million transistors per square millimeter — whereas Intel does not list transistor count or die size for its Haswell GT3e chip.

Both GPUs have 320 shading units, but the similarity ends there. The AMD part has 20 TMUs and 8 ROPs, while the Intel part has 40 TMUs and 4 ROPs. This configuration gives Intel a 125% higher texture rate (46.00 vs 20.42 GTexel/s) but AMD a 77.6% higher pixel rate (8.168 vs 4.600 GPixel/s). Clock behavior also diverges: AMD lists a base of 780 MHz and boost of 1021 MHz; Intel lists a base of 200 MHz and boost of 1150 MHz, though the memory subsystem for both is system-shared with dependent bandwidth.

API support shows a generational split. AMD supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. Intel supports DirectX 12 (11_1), OpenGL 4.3, and Vulkan 1.0 — an earlier feature set across the board. The AMD part’s bus interface is listed as IGP, while Intel uses a Ring Bus; both are integrated parts with no power connectors or dedicated display outputs (portable device dependent for AMD, motherboard dependent for Intel). Intel’s TDP is specified at 45 W, while AMD’s is absent, and both are end-of-life products, with AMD releasing in 2016 and Intel in 2013.
