AMD Radeon R7 M350 vs Intel UHD Graphics P630 Comparison

The AMD Radeon R7 M350 and Intel UHD Graphics P630 represent two very different approaches to integrated and discrete graphics. The R7 M350 is a dedicated mobile GPU built on AMD’s GCN 3.0 architecture, while the P630 is an integrated processor graphics solution from Intel’s Generation 9.5 lineup. The database records two head-to-head benchmark results, and the Radeon wins both, but the margin tells a more nuanced story.

Head-to-Head Benchmarks

In the Geekbench OpenCL test, the AMD Radeon R7 M350 scores 6991 points, while the Intel UHD Graphics P630 scores 5111 points. This gives the AMD part a 36.8% advantage, a substantial lead that reflects the fundamental difference between a dedicated GPU with its own memory and an integrated solution sharing system resources. The R7 M350’s score places it in the 36th percentile of all GPUs in the database, while the P630 sits at the 31st percentile.

The Vulkan benchmark narrows considerably. The Radeon R7 M350 scores 5662, and the Intel UHD Graphics P630 scores 5628. The delta here is only 0.6%, which is within run-to-run variation territory. This near-tie suggests that when both GPUs are pushed through the Vulkan API, the architectural differences that dominate OpenCL workloads largely disappear. The Intel part’s newer API support, including Vulkan 1.3 compared to the AMD’s Vulkan 1.2.170, may help close the gap in this particular test.

Looking at the average benchmark score across all recorded tests, the Radeon R7 M350 averages 6327 points, while the Intel UHD Graphics P630 averages 5370 points. That is an 18.4% overall difference, though the head-to-head data shows the gap is almost entirely driven by the OpenCL result. The R7 M350’s nearest rivals in the database include the AMD Radeon Pro WX 4100 with an average score of 6330 and the NVIDIA Quadro K620 at 6282, both essentially tied with the Radeon’s average. The Intel UHD Graphics P630’s nearest rivals include the AMD Radeon R7 M365X at 5416 and the AMD Radeon R7 M445 at 5358, showing it sits in a lower performance tier.

The wins tally is 2 for the Radeon and 0 for the Intel part. However, the Vulkan result at 0.6% is too close to declare a meaningful advantage. The data indicates that for OpenCL compute workloads, the R7 M350 is clearly superior, but for Vulkan graphics, the two are effectively interchangeable in performance.

Where Each One Wins

The AMD Radeon R7 M350 wins decisively in OpenCL compute. Its 36.8% lead in that test suggests it handles general-purpose GPU workloads, such as those used in rendering, simulation, or data processing, with significantly more headroom. The R7 M350 also has a higher pixel rate at 8.120 GPixel/s compared to the Intel’s 3.600 GPixel/s, and while pixel rate is not directly benchmarked here, it aligns with the OpenCL result. The Radeon’s texture rate is 24.36 GTexel/s versus 28.80 GTexel/s for the Intel part, so the Intel GPU actually edges ahead in texture fill, but that does not translate into a benchmark win.

The Intel UHD Graphics P630 wins in Vulkan parity. With a score of 5628 versus 5662, the difference is negligible. For users running Vulkan-based games or applications, the database shows no practical performance gap. The Intel part also has a higher FP16 throughput at 921.6 GFLOPS compared to the R7 M350’s 779.5 GFLOPS, and its FP16 operates at a 2:1 ratio versus the AMD’s 1:1. This suggests the Intel GPU can process half-precision data faster, though no benchmark in the database directly measures this.

For memory, the Radeon has a fixed 4 GB of DDR3 on a 64-bit bus with 16.00 GB/s bandwidth, while the Intel part uses system shared memory with system-dependent bandwidth. In practice, the dedicated memory gives the Radeon a consistency advantage, but the Intel part can leverage faster system RAM if available, which the database notes as “System Dependent.”

Specification Differences

The two GPUs differ across nearly every core specification. The Radeon R7 M350 has 384 shading units, while the Intel UHD Graphics P630 has 192 shading units, exactly half. Both have 24 texture mapping units, but the Radeon has 8 ROPs versus the Intel’s 3 ROPs. The Radeon’s pixel rate is 8.120 GPixel/s, compared to 3.600 GPixel/s for the Intel part. The texture rate flips: the Intel GPU reaches 28.80 GTexel/s, while the Radeon reaches 24.36 GTexel/s.

Clock speeds differ significantly. The Radeon runs at a base clock of 1000 MHz with a boost of 1015 MHz. The Intel part has a base clock of 350 MHz and a boost of 1200 MHz. The Intel GPU boosts much higher, but its base clock is far lower, reflecting its power management as an integrated part. The Radeon’s memory clock is 1000 MHz, translating to 2 Gbps effective, while the Intel part uses system shared memory with no dedicated clock.

Memory configuration is a major split. The Radeon has 4 GB of DDR3 on a 64-bit bus with 16.00 GB/s bandwidth. The Intel part has system shared memory, system shared type, system shared bus width, and system dependent bandwidth. The Radeon’s FP32 performance is 779.5 GFLOPS versus the Intel’s 460.8 GFLOPS. For FP16, the Radeon delivers 779.5 GFLOPS (1:1 ratio), while the Intel delivers 921.6 GFLOPS (2:1 ratio).

The power profile also differs, with the Intel part rated at 15 W TDP and listed as an IGP, while the Radeon has no recorded TDP. The Radeon uses a PCIe 3.0 x8 interface, while the Intel part uses a Ring Bus. Display outputs are not recorded for the Radeon, but the Intel part is motherboard dependent.

Architecture Differences

The AMD Radeon R7 M350 is built on the Meso chip using GCN 3.0 architecture, part of the Gem System generation (R7 M300). It is manufactured on a 28 nm process at TSMC, with 1,550 million transistors on a 125 mm² die, giving a transistor density of 12.4 million per square millimeter. The Intel UHD Graphics P630 uses the Comet Lake GT2 chip with Generation 9.5 architecture, part of the HD Graphics-W (Comet Lake) generation. It is built on a 14 nm+++ process at Intel, with no transistor or die size recorded in the database.

The Radeon supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The DirectX feature level is slightly higher on the Intel GPU, and its Vulkan version is newer. The Radeon’s production status is end-of-life, with a release date of May 4, 2015. The Intel part is also end-of-life, releasing on May 12, 2020. The Radeon lists its predecessor as Solar System and successor as Polaris Mobile, while the Intel part has no recorded predecessor or successor.

The Radeon’s FP16 operates at a 1:1 ratio with FP32, meaning no rate advantage for half-precision work. The Intel part operates at 2:1, doubling its FP16 throughput relative to FP32. This is a notable architectural difference, even though the Radeon’s raw FP32 is higher. The Intel GPU’s 24 TMUs match the Radeon’s 24 TMUs, but the Intel part has only 3 ROPs, which explains its much lower pixel rate despite a higher texture rate.

The process node difference is significant: 28 nm for AMD versus 14 nm+++ for Intel. The Intel process is newer and more power-efficient, which aligns with its 15 W TDP and integrated nature. The Radeon, as a discrete part, does not have a recorded TDP, but its dedicated memory and higher shading unit count suggest a higher power draw. The Radeon’s 1,550 million transistors are packed into 125 mm², while the Intel part has no such figures, but its integrated design shares the CPU die.

The Verdict

The data points to the AMD Radeon R7 M350 as the stronger performer overall. It wins both head-to-head benchmarks, with a 36.8% lead in OpenCL and a 0.6% lead in Vulkan. Its average benchmark score of 6327 places it well above the Intel UHD Graphics P630’s 5370. The Radeon also has double the shading units, more ROPs, dedicated 4 GB memory, and a higher pixel rate. For any workload that relies on OpenCL compute, the Radeon is the clear choice.

The Intel UHD Graphics P630 is not without merit. Its Vulkan performance is essentially tied with the Radeon, and it supports a newer Vulkan version (1.3 versus 1.2.170) and a higher DirectX feature level (12_1 versus 12_0). It also has a higher texture rate at 28.80 GTexel/s and higher FP16 throughput at 921.6 GFLOPS. Its 15 W TDP and integrated status make it far more power-efficient, and it requires no separate memory allocation beyond system shared memory.

Users who prioritize compute performance, pixel fill, or consistent memory bandwidth should select the AMD Radeon R7 M350. Its 4 GB dedicated DDR3 memory avoids the system-dependent bandwidth limitations of the Intel part, and its OpenCL lead is substantial. Users who run Vulkan-based applications exclusively will see no practical difference, as the 0.6% delta is negligible. Those who value newer API support, lower power consumption, and higher texture throughput might prefer the Intel UHD Graphics P630, especially in a system where the integrated GPU incurs no extra hardware cost.

The Radeon’s percentile standing at 36 versus the Intel’s 31 reinforces the overall performance ranking. The Radeon’s nearest rivals, such as the AMD Radeon Pro WX 4100 and NVIDIA Quadro K620, sit at nearly identical average scores, indicating it is a mid-range part from its era. The Intel’s rivals, including the AMD Radeon R7 M365X and R7 M445, are also closely matched, placing it just below the Radeon’s tier. In short, the Radeon wins on raw performance, while the Intel part wins on efficiency and modern API support. The choice depends on whether compute power or platform integration matters more.
