Where Each One Wins

The Intel UHD Graphics 730 wins both head-to-head benchmark tests recorded in the database. Its strongest margin comes in the Geekbench Vulkan test, where it posts 5870 against the AMD's 4893, a 20% lead. This indicates the Intel architecture has a clear advantage in Vulkan-based workloads, which often appear in modern game engines and compute applications.

The Intel part also edges out the AMD in Geekbench OpenCL, scoring 5988 versus 5939, a narrow 0.8% margin. While the difference is small, it shows the Intel IGP can hold its own in OpenCL compute tasks against a dedicated mobile GPU.

The AMD Radeon R7 M365X wins in areas that the head-to-head benchmarks do not directly measure. It has a higher FP32 throughput (633.6 GFLOPS), a faster texture fill rate (19.80 GTexel/s), and dedicated GDDR5 memory with 64.00 GB/s bandwidth. These specifications suggest it may have an edge in texture-heavy or memory-bandwidth-sensitive workloads, even though the recorded benchmarks favor Intel.

The AMD also has double the shading units (384 versus 192) and double the texture mapping units (24 versus 12). In theory, this gives it more parallel processing capacity for certain shader operations. However, the benchmark results do not reflect a win for the AMD in either recorded test.

Architecture Differences

The Intel UHD Graphics 730 is built on Rocket Lake silicon using Intel's Generation 12.1 architecture, fabricated on a 14 nm+++ process at Intel's own foundry. Its generation is listed as HD Graphics (Rocket Lake), and it uses a Ring Bus interface. The AMD Radeon R7 M365X uses the GCN 1.0 architecture, based on the Litho chip, manufactured on a 28 nm process by TSMC. It is part of the Gem System (R7 M300) generation and connects via PCIe 3.0 x8.

The Intel GPU integrates its memory controller with the system, using System Shared memory where bandwidth is dependent on the host platform. The AMD GPU has a discrete memory setup with 1024 MB of GDDR5, a 128-bit bus, and a fixed 64.00 GB/s bandwidth. The AMD chip contains 950 million transistors on a 77 mm² die, giving a transistor density of 12.3M / mm². The Intel part does not list transistor or die size data in the database.

In terms of API support, the Intel GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The AMD GPU supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The Intel part has a newer Vulkan version and a higher DirectX feature level. The Intel GPU also supports FP16 compute at 998.4 GFLOPS with a 2:1 ratio, while the AMD does not list FP16 capability.

The Intel GPU has a fixed TDP of 15 W and is an IGP (integrated graphics processor) with motherboard-dependent display outputs. The AMD GPU does not list a TDP, slot width, or display outputs in the database. The AMD's predecessor is listed as Solar System and its successor as Polaris Mobile, while the Intel part has no predecessor or successor listed.

Specification Differences

The two GPUs differ across nearly every core specification. The Intel UHD Graphics 730 has 192 shading units, 12 TMUs, and 8 ROPs. The AMD Radeon R7 M365X has 384 shading units, 24 TMUs, and 8 ROPs. The pixel rates are 10.40 GPixel/s for Intel and 6.600 GPixel/s for AMD. The texture rates are 15.60 GTexel/s for Intel and 19.80 GTexel/s for AMD.

FP32 performance is 499.2 GFLOPS on the Intel part versus 633.6 GFLOPS on the AMD. The Intel GPU supports FP16 at 998.4 GFLOPS, while the AMD has no FP16 data. Clock speeds differ: the Intel has a base clock of 300 MHz and a boost clock of 1300 MHz, while the AMD lists no base or boost clocks, only a memory clock of 1000 MHz (4 Gbps effective).

Memory configurations are fundamentally different. The Intel uses System Shared memory with a System Shared bus width and System Dependent bandwidth. The AMD uses 1024 MB of GDDR5 with a 128-bit bus and 64.00 GB/s bandwidth. The Intel GPU is built on a 14 nm+++ process, the AMD on 28 nm. The Intel uses a Ring Bus interface, the AMD uses PCIe 3.0 x8. The Intel has a 15 W TDP and is an IGP, while the AMD has no TDP or slot width listed.

The production status for both is end-of-life. The release dates differ: AMD on May 4, 2015, and Intel on March 29, 2021. The AMD has a transistor count of 950 million and a die size of 77 mm², while the Intel lists neither. The AMD's transistor density is 12.3M / mm².

Head-to-Head Benchmarks

The Geekbench OpenCL test shows a near tie. The Intel UHD Graphics 730 scores 5988, and the AMD Radeon R7 M365X scores 5939. The Intel wins by 0.8%. This margin is small enough that run-to-run variation could matter, but the database records the Intel as the winner.

The Geekbench Vulkan test is a decisive win for Intel. The Intel scores 5870, and the AMD scores 4893. That is a 20% difference. This is the largest gap between the two parts in any recorded benchmark. It suggests that Vulkan-based applications, which are common in modern gaming and compute, will favor the Intel solution significantly.

Looking at the nearest rivals for context, the Intel UHD Graphics 730 sits at the 33rd percentile among all GPUs, with an average benchmark score of 5929. Its closest rival is the AMD Radeon HD 8730M at 5955, which is 0.4% higher. The NVIDIA Quadro K620M scores 5957 (0.5% higher), the AMD Radeon HD 8750M scores 5970 (0.7% higher), and the NVIDIA Quadro K4000 scores 5982 (0.9% higher). So the Intel part is just below a cluster of slightly faster rivals.

The AMD Radeon R7 M365X is at the 32nd percentile, with an average benchmark score of 5416. Its nearest rivals include the AMD Radeon 610M at 5444 (0.5% higher), the Intel UHD Graphics P630 at 5370 (0.9% lower), the NVIDIA Quadro M4000 at 5467 (0.9% higher), and the AMD Radeon R7 M445 at 5358 (1.1% lower). The AMD part's average score is dragged down by its weak Vulkan result, while its OpenCL score is competitive with the Intel part.

The data shows a clear pattern: in OpenCL, the two are nearly equal, with Intel ahead by less than 1%. In Vulkan, Intel is far ahead, with a 20% lead. The AMD's higher shader count and FP32 throughput do not translate into benchmark wins in these tests.

The Verdict

The Intel UHD Graphics 730 is the better choice for anyone running Vulkan-based workloads. Its 20% lead in the Geekbench Vulkan test is substantial and consistent with its newer architecture and higher DirectX feature level. For OpenCL tasks, the two are effectively tied, with Intel holding a 0.8% edge.

The AMD Radeon R7 M365X has theoretical advantages in shading units, texture rate, and FP32 throughput, but the recorded benchmarks do not show these translating into wins. Its dedicated GDDR5 memory with 64.00 GB/s bandwidth may help in memory-bound scenarios, but the database does not include a test that favors it.

For integrated graphics, the Intel part is a 15 W IGP with no additional power connector, making it suitable for thin-and-light systems. The AMD part, as a discrete mobile GPU, may offer more raw compute headroom in theory, but its benchmark scores lag in Vulkan.

The percentile rankings reinforce this: the Intel sits at the 33rd percentile and the AMD at the 32nd, a negligible difference overall. But the per-test breakdown shows the Intel wins both recorded tests, including a decisive Vulkan victory.

A PC builder choosing between these two should pick the Intel UHD Graphics 730 if Vulkan support matters, as it clearly outperforms the AMD in that API. If OpenCL is the primary workload, the choice is nearly a coin flip, with Intel holding a slight edge. The AMD Radeon R7 M365X does not win any recorded benchmark, so there is no data-driven reason to prefer it over the Intel part.
