AMD Radeon R7 M365X vs Intel UHD Graphics P630 Comparison

AMD Radeon R7 M365X and Intel UHD Graphics P630 are near-perfect equals in average benchmark score, with the AMD part at 5416 and the Intel part at 5370, a gap of just 0.9% in AMD’s favor. The data shows a split decision across the two available tests: the R7 M365X wins Geekbench OpenCL by 16.2%, while the UHD P630 wins Geekbench Vulkan by 13.1%. With one win each and nearly identical aggregate performance, the choice comes down to software API preference, platform constraints, and the specific workload characteristics that favor each architecture.

The Verdict

The benchmark data presents a rare tie: the AMD Radeon R7 M365X and Intel UHD Graphics P630 each secure one head-to-head victory, and their average scores differ by less than 1%. For users running OpenCL-accelerated applications, the R7 M365X is the clear pick, as it posts 5939 points against Intel’s 5111 points, a 16.2% advantage. Conversely, for Vulkan-based workloads, the Intel UHD P630 takes the lead with 5628 points versus AMD’s 4893 points, a 13.1% margin. The AMD card’s average score of 5416 places it at the 32nd percentile of all GPUs, while Intel’s 5370 average sits at the 31st percentile — essentially indistinguishable in overall standing. The R7 M365X is the better choice for legacy OpenCL compute tasks and scenarios where dedicated GDDR5 memory is beneficial, while the UHD P630 suits Vulkan-centric applications and systems where an integrated GPU with 15 W power draw is preferred. Neither part dominates; the data suggests matching the GPU to the dominant API in your software stack.

Architecture Differences

The two GPUs diverge fundamentally in their underlying designs. The AMD Radeon R7 M365X uses the GCN 1.0 architecture on a 28 nm TSMC process, packing 950 million transistors into a 77 mm² die with a transistor density of 12.3 million per square millimeter. The Intel UHD Graphics P630, in contrast, is built on the Generation 9.5 architecture using Intel’s 14 nm+++ process node, with the chip identified as Comet Lake GT2. The AMD part is a discrete mobile GPU with 1024 MB of dedicated GDDR5 memory on a 128-bit bus, delivering 64.00 GB/s of bandwidth. The Intel solution is an integrated GPU (IGP) that shares system memory, with bandwidth described as “System Dependent” and no dedicated VRAM. Shading unit counts differ sharply: the R7 M365X has 384 shading units, while the UHD P630 has 192. Both have 24 texture mapping units (TMUs), but the ROP count favors AMD at 8 versus Intel’s 3. Clock behavior also differs — the Intel GPU has a base clock of 350 MHz and a boost clock of 1200 MHz, while the AMD part’s base and boost clocks are not specified in the data, only its memory clock of 1000 MHz (4 Gbps effective). API support shows a split: both support DirectX 12 and OpenGL 4.6, but AMD offers Vulkan 1.2.170 while Intel offers the newer Vulkan 1.3, and Intel’s DirectX feature level is 12_1 versus AMD’s 11_1.

Where Each One Wins

The AMD Radeon R7 M365X wins decisively in OpenCL compute workloads. Its Geekbench OpenCL score of 5939 is 16.2% higher than Intel’s 5111, reflecting the advantage of dedicated GDDR5 memory and a higher pixel rate (6.600 GPixel/s versus 3.600 GPixel/s) despite lower texture rate. The R7 M365X also has twice the shading units (384 versus 192), which likely contributes to its OpenCL strength. In contrast, the Intel UHD Graphics P630 wins in Vulkan workloads, scoring 5628 versus AMD’s 4893, a 13.1% margin. Intel’s higher texture rate (28.80 GTexel/s versus 19.80 GTexel/s) and newer Vulkan 1.3 API support (versus AMD’s 1.2.170) align with this result. The Intel part also offers FP16 performance at 921.6 GFLOPS (2:1), while the AMD part has no listed FP16 capability, which may benefit certain compute tasks. The UHD P630’s 15 W TDP and IGP form factor make it suitable for low-power systems, whereas the R7 M365X’s dedicated memory and 128-bit bus favor bandwidth-sensitive workloads. The data indicates a clear API-based split: OpenCL leans AMD, Vulkan leans Intel.

Head-to-Head Benchmarks

The two benchmark tests produce opposite winners, and the margins are significant in both directions. In Geekbench OpenCL, the AMD Radeon R7 M365X scores 5939, which is 16.2% higher than the Intel UHD Graphics P630’s 5111. This is AMD’s largest win and reflects a 828-point gap. The AMD part’s higher pixel rate (6.600 GPixel/s versus 3.600 GPixel/s) and double shading unit count likely drive this OpenCL advantage. In Geekbench Vulkan, the tables turn: Intel scores 5628 against AMD’s 4893, a 735-point difference and a 13.1% margin. Intel’s superior texture rate (28.80 GTexel/s versus 19.80 GTexel/s) and its newer Vulkan 1.3 API are probable contributors to this result. Notably, the average benchmark scores are far closer than either individual test suggests — AMD’s 5416 and Intel’s 5370 differ by only 46 points (0.9%). The R7 M365X’s nearest rival, the AMD Radeon 610M, scores 5444 (0.5% higher), while the UHD P630’s nearest rival, the AMD Radeon R7 M445, scores 5358 (0.2% lower). The data shows that each GPU’s strength is concentrated in one API, making the overall average a misleading indicator of actual performance in any given workload.

Specification Differences

The two GPUs differ across nearly every measurable specification. The AMD Radeon R7 M365X uses a 28 nm process node from TSMC, while the Intel UHD Graphics P630 uses Intel’s 14 nm+++ process. The AMD chip is named “Litho” and contains 950 million transistors on a 77 mm² die, whereas Intel’s Comet Lake GT2 has no listed transistor count or die size. Memory configurations are fundamentally different: the R7 M365X has 1024 MB of GDDR5 with a 128-bit bus and 64.00 GB/s bandwidth, while the UHD P630 has system shared memory with system-dependent bandwidth. Shading units are 384 on AMD versus 192 on Intel; TMUs are equal at 24 each; ROPs are 8 on AMD versus 3 on Intel. Pixel rate is 6.600 GPixel/s on AMD versus 3.600 GPixel/s on Intel, but texture rate reverses the trend: 19.80 GTexel/s on AMD versus 28.80 GTexel/s on Intel. FP32 performance is 633.6 GFLOPS on AMD versus 460.8 GFLOPS on Intel, while FP16 is only listed on Intel at 921.6 GFLOPS (2:1). The Intel part has a TDP of 15 W and is an IGP with a Ring Bus interface, while AMD’s TDP and bus interface are PCIe 3.0 x8. Intel’s base clock is 350 MHz with a 1200 MHz boost; AMD’s clocks are unlisted except for memory at 1000 MHz. API support differs: both have DirectX 12 and OpenGL 4.6, but AMD’s DirectX feature level is 11_1 versus Intel’s 12_1, and AMD supports Vulkan 1.2.170 versus Intel’s 1.3. Release dates are 2015-05-04 for AMD and 2020-05-12 for Intel, and both are end-of-life.
