AMD Radeon HD 7730M vs Intel UHD Graphics P750 Comparison

The AMD Radeon HD 7730M and Intel UHD Graphics P750 are remarkably close competitors in the OpenCL benchmark arena, with the data showing a virtual tie. The AMD part edges out a 0.4% lead in the sole head-to-head test, a margin so thin it falls within typical run-to-run variance. Both GPUs sit at the 38th percentile of all GPUs, indicating they occupy the same performance tier. The verdict is not about raw speed but about which architectural trade-offs suit a specific workload, as the two designs achieve parity through entirely different means: the AMD uses a dedicated 2 GB memory pool and a higher base clock, while the Intel leverages a much faster boost clock and a newer feature set.

The Verdict

The benchmark data indicates that neither GPU offers a meaningful performance advantage over the other in the single measured test. The AMD Radeon HD 7730M scores 6581, while the Intel UHD Graphics P750 scores 6554, a delta of just 0.4%. For users prioritizing raw compute throughput in OpenCL applications, the AMD card is the nominal winner, but the margin is negligible. For users who need modern API support, the Intel part is the clear choice, as it supports DirectX 12 (12_1) and Vulkan 1.4, whereas the AMD part is limited to DirectX 12 (11_1) and Vulkan 1.2.170. The Intel GPU also boasts a significantly higher pixel rate (41.60 GPixel/s vs 10.80 GPixel/s) and texture rate (83.20 GTexel/s vs 21.60 GTexel/s), which suggests it will handle fill-rate-bound tasks much better despite the similar OpenCL score. The AMD card is for legacy compatibility and dedicated memory bandwidth; the Intel is for modern API access and higher clock-speed headroom.

Architecture Differences

The fundamental architectural split is stark. The AMD Radeon HD 7730M uses the GCN 1.0 architecture on a 28 nm process from TSMC, packing 1,500 million transistors into a 123 mm² die. The Intel UHD Graphics P750 uses Intel's Generation 12.1 architecture on a 14 nm+++ process. The AMD chip features 512 shading units, 32 TMUs, and 16 ROPs, while the Intel chip has 256 shading units, 64 TMUs, and 32 ROPs. This means the Intel part has half the shading units but double the texture and pixel processing units. The AMD GPU has a dedicated 2 GB DDR3 memory with a 128-bit bus and 28.80 GB/s bandwidth, while the Intel GPU relies on System Shared memory with a System Dependent bandwidth. Clock behavior also diverges sharply: the AMD has a base clock of 575 MHz and a boost of 675 MHz, while the Intel has a base of 350 MHz but a boost of 1300 MHz, nearly double the AMD's peak. The Intel part also supports FP16 with a 2:1 ratio (1,331.2 GFLOPS), a feature entirely absent from the AMD's spec sheet. The AMD's TDP is 25 W versus the Intel's 15 W, making the Intel part more power-efficient on paper.

Specification Differences

The two GPUs differ across nearly every core specification. The AMD Radeon HD 7730M has 512 shading units, 32 TMUs, and 16 ROPs, while the Intel UHD Graphics P750 has 256 shading units, 64 TMUs, and 32 ROPs. The AMD's process node is 28 nm from TSMC, while the Intel uses 14 nm+++ from Intel. The AMD die size is 123 mm² with 1,500 million transistors, while the Intel has no listed die or transistor count. Clock speeds differ: AMD base 575 MHz and boost 675 MHz versus Intel base 350 MHz and boost 1300 MHz. Memory configurations are completely different, with the AMD using dedicated 2 GB DDR3 at 1800 Mbps effective on a 128-bit bus, versus the Intel's System Shared memory. Pixel rate favors the Intel massively at 41.60 GPixel/s versus 10.80 GPixel/s, as does texture rate at 83.20 GTexel/s versus 21.60 GTexel/s. FP32 compute is close, with the AMD at 691.2 GFLOPS and the Intel at 665.6 GFLOPS, but the Intel adds FP16 throughput at 1,331.2 GFLOPS. The AMD has a TDP of 25 W, while the Intel is 15 W. The AMD uses a PCIe 2.0 x16 bus interface, while the Intel uses a Ring Bus and is an IGP (integrated graphics processor). The AMD supports DirectX 12 (11_1) and Vulkan 1.2.170, while the Intel supports DirectX 12 (12_1) and Vulkan 1.4.

Head-to-Head Benchmarks

The only benchmark available is Geekbench OpenCL, where the AMD Radeon HD 7730M scores 6581 against the Intel UHD Graphics P750's 6554. The AMD wins by 0.4%, which is a single-point margin in practical terms. This result puts the AMD 0.4% ahead of its nearest rival, the Intel, and 0.5% behind the AMD Radeon R7 M460, which scores 6612. The Intel, conversely, is 0.4% behind the AMD and 0.6% ahead of the NVIDIA GeForce GTX 670M, which scores 6513. Both GPUs also trail the NVIDIA GeForce GT 555M by 1.4% and 0.9% respectively, with the GT 555M scoring 6493. The data shows a tight cluster of four GPUs (the two in question plus the R7 M460 and GTX 670M) all within a 1.5% range of each other, making the AMD vs Intel matchup one of the closest in the database.

Where Each One Wins

The AMD Radeon HD 7730M wins in raw OpenCL compute, as its 6581 score edges out the Intel's 6554. It also holds a lead in FP32 throughput at 691.2 GFLOPS versus 665.6 GFLOPS, and it offers dedicated memory with a fixed 28.80 GB/s bandwidth, which can be more predictable than system-shared memory. The AMD also has a higher base clock (575 MHz), which may help in sustained workloads that don't trigger boost behavior.

The Intel UHD Graphics P750 wins decisively in pixel and texture throughput, with a pixel rate of 41.60 GPixel/s (385% higher) and a texture rate of 83.20 GTexel/s (385% higher) compared to the AMD's 10.80 GPixel/s and 21.60 GTexel/s. This makes the Intel part far superior for fill-rate-bound tasks like resolution scaling or post-processing effects. The Intel also wins on API support, offering DirectX 12 (12_1) and Vulkan 1.4, which are newer specifications than the AMD's DirectX 12 (11_1) and Vulkan 1.2.170. The Intel GPU also has a much higher boost clock at 1300 MHz, which can deliver burst performance in short workloads. For power-constrained environments, the Intel's 15 W TDP is lower than the AMD's 25 W. Finally, the Intel's FP16 support at 1,331.2 GFLOPS gives it an edge in workloads that can leverage half-precision arithmetic, a feature the AMD lacks entirely.
