AMD Radeon HD 8730M vs Intel UHD Graphics P750 Comparison

The Intel UHD Graphics P750 and the AMD Radeon HD 8730M represent two very different approaches to mobile graphics. One is an integrated processor graphics solution built into a modern CPU, while the other is a discrete mobile GPU from an older generation. The benchmark data in the database shows a clear, though not overwhelming, winner in overall compute performance.

Head-to-Head Benchmarks

The primary benchmark recorded for both graphics solutions is Geekbench OpenCL, which measures general-purpose compute performance. In this test, the Intel UHD Graphics P750 scores 6554 points, while the AMD Radeon HD 8730M scores 5955 points. This gives the Intel solution a 10.1% advantage over the AMD part in this specific workload. The Intel UHD Graphics P750 wins the only head-to-head benchmark recorded in the database.

Looking at the broader competitive landscape, these scores place both GPUs in a similar performance tier. The Intel UHD Graphics P750 sits at the 38th percentile of all GPUs in the database. Its nearest rivals, according to the recorded data, include the AMD Radeon HD 7730M which scores 6581, a figure 0.4% higher than the Intel part. The NVIDIA GeForce GTX 670M scores 6513, which is 0.6% lower. The AMD Radeon R7 M460 scores 6612, putting it 0.9% ahead, while the NVIDIA GeForce GT 555M scores 6493, which is 0.9% behind. This clustering shows the Intel UHD Graphics P750 is operating right at the edge of a tightly packed group of older discrete mobile graphics processors.

The AMD Radeon HD 8730M, with its score of 5955, sits at the 34th percentile of all GPUs. Its nearest rivals are similarly close. The NVIDIA Quadro K620M scores 5957, essentially tied with the AMD part at a 0% delta. The AMD Radeon HD 8750M scores 5970, which is 0.3% higher. The Intel UHD Graphics 730 scores 5929, 0.4% lower, and the NVIDIA Quadro K4000 scores 5982, 0.5% higher. This data indicates that the Radeon HD 8730M is positioned within a very narrow performance band, with all four of its closest rivals within a half a percent of its score.

The 10.1% delta between the two comparison subjects is significant within their respective peer groups. For instance, the gap between the Intel UHD Graphics P750 and its closest rival, the AMD Radeon HD 7730M, is only 0.4%. The gap between the AMD Radeon HD 8730M and its closest rival, the NVIDIA Quadro K620M, is essentially zero. Therefore, the performance difference between the P750 and the HD 8730M is much larger than the typical spread seen among their respective nearest competitors, making the Intel part a clear step up in this compute workload.

Where Each One Wins

Based on the recorded benchmarks, the Intel UHD Graphics P750 is the outright winner in the only test conducted. This gives it a single win in the head-to-head comparison. It demonstrates superior OpenCL compute capability, which is relevant for applications that offload parallel processing tasks to the GPU. This includes some video encoding, image processing, and general-purpose computing tasks that can leverage the GPU's shader array.

The AMD Radeon HD 8730M, in contrast, does not win any benchmark in the head-to-head comparison. While it is a discrete GPU with its own dedicated video memory, the database records show it trailing the Intel solution in raw compute throughput. Its advantage, if any, lies outside of the measured OpenCL performance. The data does not record wins for the AMD part in any specific workload category.

The distinction is important for use-case analysis. For a user whose primary concern is compute performance, the data clearly points to the Intel UHD Graphics P750. Its higher score in Geekbench OpenCL suggests it can handle compute shaders and general-purpose GPU tasks more effectively than the Radeon HD 8730M. The AMD part, despite being a discrete solution, does not translate that hardware design into a compute performance advantage in this test. Its performance characteristics may be better suited to other tasks not covered by the single benchmark in the database.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process technologies. The Intel UHD Graphics P750 is based on the "Rocket Lake" chip and uses the Generation 12.1 architecture. It is manufactured on Intel's 14 nm+++ process node at Intel's own foundry. This is an integrated graphics processor (IGP), meaning it is built into the CPU and shares system resources.

The AMD Radeon HD 8730M is based on the "Mars" chip and uses the GCN 1.0 architecture. It is manufactured on a 28 nm process node at TSMC. The chip contains 950 million transistors on a die size of 77 mm², giving it a transistor density of 12.3M per mm². This is a discrete mobile GPU, designed as a separate chip with its own dedicated memory.

The differences extend to the core configuration. The Intel UHD Graphics P750 has 256 shading units, 64 texture mapping units (TMUs), and 32 ROPs. The AMD Radeon HD 8730M has 384 shading units, but only 24 TMUs and 8 ROPs. This is a notable split: the AMD part has more shader processors, but the Intel part has significantly more texture units and ROPs. This configuration suggests the Intel solution is designed to handle texture-heavy and pixel-heavy workloads efficiently, while the AMD part may rely more on its raw shader count.

Clock speeds also differ considerably. The Intel UHD Graphics P750 has a base clock of 350 MHz and a boost clock of 1300 MHz. The AMD Radeon HD 8730M has a base clock of 650 MHz and a boost clock of 700 MHz. The Intel part has a much higher boost clock, which likely contributes to its performance advantage despite having fewer shading units.

Memory configurations are starkly different. The Intel UHD Graphics P750 uses system shared memory, with the bus width also listed as system shared and bandwidth described as system dependent. The AMD Radeon HD 8730M has 2 GB of dedicated DDR3 memory on a 128-bit bus, providing a bandwidth of 28.80 GB/s. The memory clock for the AMD part is 900 MHz, which translates to 1800 Mbps effective. This dedicated memory is a key architectural advantage for the discrete AMD part, providing it with predictable bandwidth that does not compete with the CPU for system memory access.

The compute capabilities also show a divergence. The Intel UHD Graphics P750 is rated for a pixel rate of 41.60 GPixel/s and a texture rate of 83.20 GTexel/s. Its FP32 performance is 665.6 GFLOPS, and its FP16 performance is 1,331.2 GFLOPS, operating at a 2:1 ratio. The AMD Radeon HD 8730M has a pixel rate of 5.600 GPixel/s and a texture rate of 16.80 GTexel/s. Its FP32 performance is 537.6 GFLOPS. No FP16 performance is listed for the AMD part. These throughput figures align with the benchmark results, showing the Intel part has a clear advantage in pixel fill, texture processing, and raw floating-point compute.
