AMD Radeon R5 M240 vs Intel UHD Graphics P750 Comparison

The AMD Radeon R5 M240 and Intel UHD Graphics P750 are both end-of-life integrated and entry-level mobile graphics solutions, but they represent fundamentally different approaches to graphics. The data shows the AMD part holds a narrow lead in raw compute performance, while the Intel part offers a more modern feature set and significantly higher fill rates. This analysis breaks down the benchmark results, architectural differences, and practical implications for each GPU.

Where Each One Wins

Based on the single OpenCL benchmark in the data, the AMD Radeon R5 M240 wins the only head-to-head comparison. Its Geekbench OpenCL score of 6975 edges out the Intel UHD Graphics P750’s 6554 by a 6.4% margin. This makes the AMD part the clear winner for compute-heavy workloads that rely on general-purpose GPU processing, such as OpenCL-accelerated applications.

However, the Intel UHD Graphics P750 wins in several architectural categories that matter for different use cases. Its pixel rate of 41.60 GPixel/s is dramatically higher than the AMD’s 8.240 GPixel/s, which means the Intel part is far better suited for fill-rate-bound scenarios like high-resolution texture mapping or basic 2D/3D rasterization. Similarly, the Intel GPU’s texture rate of 83.20 GTexel/s dwarfs the AMD’s 20.60 GTexel/s, giving it a major advantage in texture-heavy scenes.

The Intel part also wins on API support. It supports DirectX 12 (12_1) and Vulkan 1.4, while the AMD part is limited to DirectX 12 (11_1) and Vulkan 1.2.170. For modern games or applications that leverage the latest graphics APIs, the Intel GPU has a clear compatibility edge. The AMD part counters with a higher base clock (1000 MHz vs 350 MHz) and boost clock (1030 MHz vs 1300 MHz), but the Intel part’s higher boost clock suggests it can scale further under load.

Architecture Differences

The two GPUs come from completely different design philosophies. The AMD Radeon R5 M240 uses the GCN 1.0 architecture built on a 28 nm process at TSMC, with a chip codenamed Jet. It belongs to the Gem System (R5 M200) generation. The Intel UHD Graphics P750 uses the Generation 12.1 architecture on Intel’s 14 nm+++ process, with a Rocket Lake chip from the HD Graphics-W (Rocket Lake) generation.

The AMD chip packs 690 million transistors into a 56 mm² die, yielding a transistor density of 12.3M / mm². Intel does not disclose transistor count or die size for its part, but the 14 nm+++ process suggests a much denser design. The AMD GPU has 320 shading units, 20 texture mapping units (TMUs), and 8 render output units (ROPs). The Intel GPU has fewer shading units at 256, but more than triple the TMUs at 64 and quadruple the ROPs at 32.

Memory architecture differs drastically. The AMD Radeon R5 M240 uses dedicated 1024 MB of DDR3 memory on a 64-bit bus, delivering 14.40 GB/s of bandwidth. The Intel UHD Graphics P750 uses system-shared memory, with type, bus width, and bandwidth all listed as "System Shared" or "System Dependent." This means the Intel part’s memory performance varies with the host system, while the AMD part has predictable, fixed bandwidth.

Compute capabilities show a mixed picture. The AMD part delivers 659.2 GFLOPS of FP32 performance, slightly ahead of the Intel’s 665.6 GFLOPS. However, the Intel part supports FP16 at 1,331.2 GFLOPS (2:1), while the AMD part lists no FP16 support at all. The Intel GPU also has a much higher pixel rate (41.60 GPixel/s vs 8.240 GPixel/s) and texture rate (83.20 GTexel/s vs 20.60 GTexel/s), driven by its larger TMU and ROP counts.

Power and form factor differ significantly. The Intel UHD Graphics P750 is an integrated GPU (IGP) with a 15 W TDP, making it suitable for low-power systems. The AMD Radeon R5 M240 lists no TDP, but as a discrete mobile chip it typically requires its own power allocation. The AMD part uses a PCIe 3.0 x8 bus interface, while the Intel part connects via a Ring Bus, which is standard for integrated graphics. Display outputs are unspecified for AMD but "Motherboard Dependent" for Intel.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and it shows a narrow but clear AMD victory. The AMD Radeon R5 M240 scores 6975, while the Intel UHD Graphics P750 scores 6554. This is a 6.4% delta in favor of AMD, which is a meaningful gap in compute performance.

Looking at the nearest rivals for each card puts this in context. The AMD Radeon R5 M240’s score of 6975 places it within 0.4% of the NVIDIA GeForce GTX 675M (6946) and within 0.7% of the NVIDIA GeForce GTX 680M (7023). It is also 2.1% ahead of the AMD FirePro M5100 (6830) and 0.8% behind the NVIDIA T600 (7035). This suggests the AMD part performs roughly on par with mid-range mobile GPUs from a few years ago.

The Intel UHD Graphics P750’s score of 6554 is similarly competitive. It sits 0.4% behind the AMD Radeon HD 7730M (6581) and 0.9% behind the AMD Radeon R7 M460 (6612). It is 0.6% ahead of the NVIDIA GeForce GTX 670M (6513) and 0.9% ahead of the NVIDIA GeForce GT 555M (6493). The Intel part’s percentile rank of 38 places it just below the AMD part’s percentile of 39, reinforcing the narrow overall performance gap.

The deltaPct values in the head-to-head show that the 6.4% AMD advantage is the single biggest performance difference between the two cards in any benchmark. In fill-rate and texture-rate metrics, however, the Intel part wins by much larger margins — over 400% in both cases — though these are architectural specifications rather than measured benchmarks.

The Verdict

For compute-centric workloads, the AMD Radeon R5 M240 is the better choice. Its 6.4% lead in OpenCL performance is consistent across its nearest rivals, and its dedicated memory subsystem provides predictable bandwidth. The AMD part also holds a slight edge in FP32 throughput (659.2 GFLOPS vs 665.6 GFLOPS — effectively a tie) but wins on shading unit count.

For graphics rendering and modern API support, the Intel UHD Graphics P750 is clearly superior. Its pixel rate of 41.60 GPixel/s and texture rate of 83.20 GTexel/s are over five times and four times higher, respectively, than the AMD part’s figures. This translates to better performance in resolution-scaling, texture-heavy scenes, and any workload that stresses the ROPs or TMUs. The Intel part’s support for DirectX 12 (12_1) and Vulkan 1.4 also means better compatibility with modern games and applications.

The Intel GPU’s 15 W TDP and integrated form factor make it a far better fit for thin-and-light laptops or low-power systems, while the AMD part’s PCIe 3.0 x8 interface suggests it was designed for more traditional mobile implementations. The AMD part’s release date of September 2014 also makes it older, though the Intel part’s release date is unspecified.

In a direct choice: pick the AMD Radeon R5 M240 if you need raw compute performance and dedicated memory. Pick the Intel UHD Graphics P750 if you need superior fill rates, modern API support, and lower power consumption. The benchmark data shows the AMD part wins the only measured test, but the architectural data shows the Intel part dominates in every rasterization metric.
