AMD Radeon R7 M465 vs Intel UHD Graphics P630 Comparison

Where Each One Wins

The AMD Radeon R7 M465 takes the single recorded head-to-head benchmark, the Geekbench OpenCL test, with a score of 5841 against the Intel UHD Graphics P630's 5111. That is a 14.3% advantage for the AMD part, and it is the only direct comparison available in the database. The Intel UHD Graphics P630 has no benchmark wins in the head-to-head data, though it does have a separate Vulkan score of 5628 that the AMD part does not have a recorded result for.

For compute-heavy workloads that rely on OpenCL, the AMD Radeon R7 M465 is the stronger pick. Its 384 shading units and 786.4 GFLOPS of FP32 performance give it a clear edge in raw parallel throughput. The Intel part counters with a higher boost clock of 1200 MHz versus 1024 MHz on the AMD, but it only has 192 shading units, which explains why it falls behind in the OpenCL test despite the clock advantage. The Intel GPU also supports Vulkan 1.3, while the AMD part is limited to Vulkan 1.2.170, so applications that lean heavily on the newest Vulkan features may favor the Intel solution, but the database shows no Vulkan result for the AMD part to confirm this in practice.

The Intel UHD Graphics P630 operates as an integrated processor graphics solution with a 15 W TDP, making it suitable for systems where power draw is a concern. The AMD Radeon R7 M465 does not have a TDP listed in the database, so no direct power comparison is possible. What is clear is that the AMD part wins the only benchmark where both are measured, and the Intel part has no recorded wins at all.

Architecture Differences

The AMD Radeon R7 M465 uses the GCN 3.0 architecture on a 28 nm TSMC process with a chip called Topaz. It packs 1,550 million transistors into a 125 mm² die, giving a transistor density of 12.4 million per square millimeter. The Intel UHD Graphics P630 uses the Generation 9.5 architecture on Intel's 14 nm+++ process with a Comet Lake GT2 chip. The Intel part has no transistor count, die size, or transistor density listed in the database, so those figures cannot be compared.

The memory subsystems are fundamentally different. The AMD Radeon R7 M465 has 2 GB of dedicated GDDR5 memory on a 64-bit bus, delivering 36.00 GB/s of bandwidth. The Intel UHD Graphics P630 uses system shared memory, with its bandwidth described as system dependent. This means the Intel GPU's memory performance depends entirely on the host system's RAM configuration, while the AMD card has fixed, dedicated memory resources.

The compute units differ significantly. The AMD part has 384 shading units, 24 texture mapping units, and 8 ROPs. The Intel part has 192 shading units, 24 texture mapping units, and only 3 ROPs. The AMD card achieves a pixel rate of 8.192 GPixel/s and a texture rate of 24.58 GTexel/s. The Intel GPU manages 3.600 GPixel/s and 28.80 GTexel/s. So the AMD part is more than twice as fast at pixel fill, while the Intel part has a slight edge in texture fill rate.

The FP16 and FP32 ratios also differ. The AMD Radeon R7 M465 performs FP16 at a 1:1 ratio with FP32, both at 786.4 GFLOPS. The Intel UHD Graphics P630 performs FP16 at a 2:1 ratio, giving 921.6 GFLOPS of FP16 against 460.8 GFLOPS of FP32. This means the Intel part has a higher peak FP16 throughput, but the AMD card has 70.6% more FP32 throughput.

The bus interfaces are different too. The AMD card uses PCIe 3.0 x8, while the Intel IGP connects through a Ring Bus. The Intel part is listed as an IGP slot width, meaning it is integrated into the processor package, while the AMD card is a discrete mobile GPU.

Head-to-Head Benchmarks

The database records only one head-to-head benchmark between these two parts: Geekbench OpenCL. The AMD Radeon R7 M465 scores 5841, the Intel UHD Graphics P630 scores 5111. That is a 14.3% delta in favor of the AMD card. This is a substantial margin for a single compute test, and it lines up with the raw specifications. The AMD part has twice the shading units, 384 versus 192, and 70.6% more FP32 throughput, 786.4 GFLOPS versus 460.8 GFLOPS. The Intel part has a higher boost clock, 1200 MHz versus 1024 MHz, and a higher texture rate, 28.80 GTexel/s versus 24.58 GTexel/s, but those advantages are not enough to overcome the compute deficit.

To put the AMD part's score in context, its nearest rivals include the AMD Radeon R5 M435 at 5859, which is 0.3% ahead, and the Intel UHD Graphics 730 at 5929, which is 1.5% ahead. The NVIDIA GeForce GTX 550 Ti scores 5731, which is 1.9% behind the R7 M465. The AMD Radeon HD 8730M scores 5955, which is 1.9% ahead. So the R7 M465 sits in a tight cluster of GPUs around the 5800 to 5950 score range, and its 5841 score is competitive with that group.

The Intel UHD Graphics P630's nearest rivals are a different set. The AMD Radeon R7 M445 scores 5358, which is 0.2% behind the Intel part. The AMD Radeon R7 M365X scores 5416, which is 0.8% ahead. The NVIDIA GeForce 840M scores 5322, which is 0.9% behind, and the NVIDIA GeForce 930A scores 5317, which is 1% behind. The Intel part's average benchmark score of 5370 places it in this lower performance tier, 8.8% below the AMD R7 M465's average of 5841.

The Intel part's Vulkan score of 5628 is notable because it is higher than its OpenCL score of 5111. This suggests the Intel GPU performs relatively better under Vulkan than under OpenCL, though without an AMD Vulkan result, no direct comparison is possible. What the recorded data shows is that the AMD part wins the only shared test, and it does so by a clear margin.

The Verdict

The data points to a simple conclusion for compute workloads: the AMD Radeon R7 M465 is the faster GPU. It wins the only head-to-head benchmark available, Geekbench OpenCL, by 14.3%. It has double the shading units, 384 versus 192, and significantly higher FP32 throughput, 786.4 GFLOPS versus 460.8 GFLOPS. Its pixel rate of 8.192 GPixel/s is more than double the Intel part's 3.600 GPixel/s. The AMD part also sits at the 33rd percentile of all GPUs, two points higher than the Intel part's 31st percentile.

The Intel UHD Graphics P630 has some advantages worth noting. It has a higher boost clock, 1200 MHz versus 1024 MHz, and a higher texture rate, 28.80 GTexel/s versus 24.58 GTexel/s. It supports Vulkan 1.3, a newer version than the AMD part's Vulkan 1.2.170. It is an integrated solution with a 15 W TDP, which makes it a fit for systems where a discrete GPU is not an option. Its FP16 throughput of 921.6 GFLOPS is higher than the AMD part's 786.4 GFLOPS, though the AMD part matches its FP16 and FP32 rates at 1:1, while the Intel part has a 2:1 ratio.

For a user who needs raw OpenCL compute performance from a discrete mobile GPU, the AMD Radeon R7 M465 is the clear choice based on the recorded benchmarks. For a user who needs an integrated graphics solution with a low 15 W TDP and newer API support like Vulkan 1.3, the Intel UHD Graphics P630 is the only option between these two, since the AMD part is a discrete card with no TDP listed. The Intel part also has a Vulkan score of 5628 in the database, which is higher than its OpenCL score, suggesting it handles Vulkan workloads better than OpenCL ones. But in the only test where both parts are measured against each other, the AMD Radeon R7 M465 wins decisively.
