AMD Radeon HD 8750M vs Intel UHD Graphics P630 Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear winner in the only shared test. In Geekbench OpenCL, the AMD Radeon HD 8750M scores 5970, while the Intel UHD Graphics P630 scores 5111. That is a 16.8% advantage for the AMD part, a substantial margin in raw compute performance. The Intel integrated solution trails by nearly 860 points, which translates to a meaningful gap in workloads that rely on OpenCL acceleration.

Looking at the broader database context, the AMD Radeon HD 8750M holds a 34th percentile ranking among all GPUs, while the Intel UHD Graphics P630 sits at the 31st percentile. The three-point percentile gap reinforces what the head-to-head delta shows: these are both entry-level parts, but the AMD discrete GPU occupies a slightly higher tier of performance. The Intel part does have an additional Geekbench Vulkan score of 5628, which shows it can perform better under that API than it does under OpenCL, but no Vulkan result is recorded for the AMD side, so a direct comparison is not possible from the database.

The AMD Radeon HD 8750M's nearest rivals in the database include the NVIDIA Quadro K4000 at 5982 (-0.2%), the NVIDIA Quadro K4000M at 5986 (-0.3%), the NVIDIA Quadro K620M at 5957 (+0.2%), and the AMD Radeon HD 8730M at 5955 (+0.3%). This clustering within a 31-point range indicates that the HD 8750M sits right at the center of a tight performance band, with negligible differences separating it from those competitors. The Intel UHD Graphics P630, by contrast, is surrounded by the AMD Radeon R7 M445 at 5358 (+0.2%), the AMD Radeon R7 M365X at 5416 (-0.8%), the NVIDIA GeForce 840M at 5322 (+0.9%), and the NVIDIA GeForce 930A at 5317 (+1%). The Intel part's 5370 average score places it in a similar density of rivals, but roughly 600 points below the AMD HD 8750M's neighborhood.

Where Each One Wins

The AMD Radeon HD 8750M wins the only directly comparable benchmark, the Geekbench OpenCL test, by 16.8%. That makes it the stronger choice for any application that leverages OpenCL compute, which includes tasks like video encoding assistance, image processing filters, and certain scientific or engineering calculations. The discrete nature of the GPU means it has its own dedicated memory allocation, 1024 MB of DDR3 on a 128-bit bus, which provides 28.80 GB/s of bandwidth. This dedicated memory avoids the contention that shared-memory designs face when the CPU and GPU compete for the same system RAM.

The Intel UHD Graphics P630, while losing the OpenCL comparison, shows a different strength: its Geekbench Vulkan score of 5628 is higher than its own OpenCL score of 5111, a gain of roughly 10%. This indicates that the Intel architecture responds better to the Vulkan API, which could matter in modern games or compute applications that use Vulkan. However, without a Vulkan result for the AMD part, the database cannot confirm whether the AMD GPU would outperform the Intel part under that API as well.

For general desktop usage, the Intel solution benefits from being integrated into the processor with a low 15 W TDP, making it suitable for thin-and-light laptops where power draw is a primary concern. The AMD Radeon HD 8750M has no TDP recorded in the database, but as a discrete mobile GPU from 2013, it would typically require more power and generate more heat. The Intel part also supports DirectX 12 (12_1) and Vulkan 1.3, while the AMD part supports DirectX 12 (11_1) and Vulkan 1.2.170, giving Intel a newer API feature set.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon HD 8750M uses the GCN 1.0 architecture on a 28 nm process from TSMC, with 950 million transistors packed into a 77 mm² die, yielding a transistor density of 12.3 million per square millimeter. The Intel UHD Graphics P630 uses the Generation 9.5 architecture on Intel's 14 nm+++ process, though the database records no transistor count, die size, or density for the Intel part.

The compute configuration differs significantly. The AMD GPU has 384 shading units, 24 texture mapping units, and 8 raster operation pipelines. The Intel GPU has 192 shading units, 24 texture mapping units, and only 3 raster operation pipelines. Despite having half the shading units, the Intel part matches the AMD part in TMUs, which explains why the texture rates are close: 19.80 GTexel/s for AMD versus 28.80 GTexel/s for Intel. The Intel part actually wins the texture rate comparison because its higher boost clock compensates for the lower shader count. However, the pixel rate tells a different story: the AMD part delivers 6.600 GPixel/s, while the Intel part delivers only 3.600 GPixel/s, a consequence of having just 3 ROPs compared to 8.

The clock speeds reveal a stark difference in design targets. The AMD Radeon HD 8750M runs at a base clock of 775 MHz with a boost up to 825 MHz, while the Intel UHD Graphics P630 runs at a base of 350 MHz with a boost of 1200 MHz. The Intel part relies on a much higher boost clock to extract performance from fewer execution units, whereas the AMD part uses a more balanced approach with a higher base clock and a modest boost.

Memory architecture diverges completely. The AMD GPU has dedicated 1024 MB of DDR3 with a 128-bit bus and 28.80 GB/s bandwidth, while the Intel GPU uses system-shared memory with system-dependent bandwidth. This gives the AMD part predictable memory performance, whereas the Intel part's performance depends heavily on the host system's memory configuration.

The Verdict

The data points to a straightforward conclusion for compute workloads: the AMD Radeon HD 8750M is the faster GPU. Its 16.8% OpenCL advantage over the Intel UHD Graphics P630 is substantial and consistent with its higher percentile ranking (34th versus 31st). The AMD part's dedicated memory, higher pixel rate, and greater shader count make it the better choice for GPU-accelerated tasks that respond well to raw compute throughput.

The Intel UHD Graphics P630, however, is not without merit. Its higher Vulkan score of 5628 compared to its OpenCL score of 5111 suggests it can perform better in Vulkan-based applications. Its 15 W TDP makes it far more power-efficient for mobile devices, and its newer DirectX 12 (12_1) and Vulkan 1.3 support give it a more modern API feature set. The Intel part also has a higher texture rate of 28.80 GTexel/s, which could benefit texture-heavy workloads despite the lower pixel rate.

For users who need maximum compute performance in OpenCL-based applications, the AMD Radeon HD 8750M is the clear pick. For users who prioritize power efficiency, modern API support, and Vulkan performance, the Intel UHD Graphics P630 has advantages that the benchmark numbers alone do not capture. The database records one win for AMD and zero for Intel in direct head-to-head tests, which settles the performance question, but the Intel part's architectural strengths should not be dismissed entirely.
