Architecture Differences

The two GPUs come from fundamentally different design generations. The Intel UHD Graphics 730 is built on Generation 12.1 architecture and uses the Rocket Lake chip, manufactured on Intel's 14 nm+++ process node. The AMD Radeon R7 M445 uses GCN 3.0 architecture with the Meso chip, built by TSMC on a 28 nm process. The Intel part integrates 192 shading units, 12 TMUs, and 8 ROPs, while the AMD part packs 320 shading units, 20 TMUs, and 8 ROPs. Despite having fewer shaders and TMUs, the Intel GPU posts higher benchmark scores, indicating that architecture efficiency and clock behavior compensate for the raw unit deficit.

Clock speeds differ substantially. The Intel UHD Graphics 730 runs at a base clock of 300 MHz with a boost of 1300 MHz. The AMD Radeon R7 M445 has a base clock of 780 MHz and a boost of 920 MHz. The Intel part's much higher boost ceiling helps explain its lead in pixel rate (10.40 GPixel/s versus 7.360 GPixel/s) despite having the same number of ROPs. The texture rate tells a different story: the AMD part reaches 18.40 GTexel/s because of its 20 TMUs, while the Intel part manages 15.60 GTexel/s with 12 TMUs.

Memory architecture is a major differentiator. The AMD Radeon R7 M445 has dedicated 4 GB GDDR5 memory on a 64-bit bus with 32.00 GB/s bandwidth. The Intel UHD Graphics 730 has no dedicated memory; it relies on system shared memory with system dependent bandwidth. This gives the AMD part a dedicated memory pool, though the narrow 64-bit bus limits total throughput. The Intel part's memory performance is tied to the host system's memory configuration.

The floating-point compute profile also differs. The Intel UHD Graphics 730 delivers 499.2 GFLOPS in FP32 and 998.4 GFLOPS in FP16 with a 2:1 ratio, showing support for packed half-precision compute. The AMD Radeon R7 M445 delivers 588.8 GFLOPS in FP32 and the same 588.8 GFLOPS in FP16 with a 1:1 ratio, indicating no packed FP16 advantage. The AMD part actually has higher raw FP32 throughput, but the benchmark results favor Intel overall.

Process technology and manufacturing also separate these parts. The Intel GPU uses a 14 nm+++ process from Intel's own foundry, while the AMD GPU uses a 28 nm process from TSMC. The AMD chip has 1,550 million transistors on a 125 mm² die, with a transistor density of 12.4M / mm². The Intel chip's transistor count and die size are not recorded in the database. The AMD part also has a documented predecessor (Solar System) and successor (Polaris Mobile), while the Intel part lists neither.

The bus interface differs as well: the Intel UHD Graphics 730 uses a Ring Bus interface, while the AMD Radeon R7 M445 uses PCIe 3.0 x8. Both are integrated-class parts (IGP slot width), and display connectivity is platform dependent for both: motherboard dependent for Intel, portable device dependent for AMD. The Intel part carries a 15 W TDP, while the AMD part's TDP is not recorded.

The Verdict

The recorded data points to the Intel UHD Graphics 730 as the stronger performer in this matchup. Its average benchmark score of 5929 versus 5358 for the AMD Radeon R7 M445 gives it an 11.8% lead in the head-to-head Geekbench OpenCL test. The Intel part also ranks in the 33rd percentile among all GPUs, compared to the 31st percentile for the AMD part. Users prioritizing compute benchmark results should favor the Intel UHD Graphics 730.

The AMD Radeon R7 M445 is not without its advantages. It brings dedicated GDDR5 memory, 320 shading units, and higher raw FP32 throughput (588.8 GFLOPS versus 499.2 GFLOPS). Its texture rate of 18.40 GTexel/s beats the Intel part's 15.60 GTexel/s. For workloads that stress texture fetch or benefit from dedicated memory, the AMD part could be the better choice. The data also shows the AMD part has a wider API support window for DirectX 12 (12_0), though Intel supports the higher 12_1 feature level.

The choice depends on the workload. For general compute benchmarks and OpenCL performance, the Intel UHD Graphics 730 is the clear winner. For texture-heavy tasks or scenarios where dedicated VRAM matters, the AMD Radeon R7 M445 offers structural advantages. Both parts are end-of-life products, so availability is secondary to the performance profile. The benchmark database records one win for Intel and zero for AMD in head-to-head testing.

Specification Differences

The two GPUs differ across nearly every major specification category. The Intel UHD Graphics 730 uses a 14 nm+++ process from Intel, while the AMD Radeon R7 M445 uses a 28 nm process from TSMC. The AMD chip measures 125 mm² with 1,550 million transistors and a density of 12.4M / mm²; the Intel chip's dimensions and transistor count are not recorded.

Clock behavior differs significantly. Intel runs at 300 MHz base and 1300 MHz boost, while AMD runs at 780 MHz base and 920 MHz boost. The AMD part has dedicated memory: 4 GB GDDR5 on a 64-bit bus with 32.00 GB/s bandwidth. The Intel part uses system shared memory with system dependent bandwidth.

Shader resources favor AMD: 320 shading units and 20 TMUs versus 192 shading units and 12 TMUs. Both have 8 ROPs. Pixel rate favors Intel at 10.40 GPixel/s versus 7.360 GPixel/s, while texture rate favors AMD at 18.40 GTexel/s versus 15.60 GTexel/s. FP32 compute favors AMD at 588.8 GFLOPS versus 499.2 GFLOPS, but FP16 favors Intel at 998.4 GFLOPS versus 588.8 GFLOPS.

API support differs in DirectX and Vulkan. Intel supports DirectX 12 (12_1) and Vulkan 1.4; AMD supports DirectX 12 (12_0) and Vulkan 1.2.170. Both support OpenGL 4.6. The bus interface differs: Intel uses Ring Bus, AMD uses PCIe 3.0 x8. The Intel part has a recorded 15 W TDP; the AMD part's TDP is not listed. Both are IGP slot width with platform-dependent display outputs. Release dates differ by about five years: Intel launched on 2021-03-29, AMD on 2016-05-14. Both are end-of-life.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL, and the Intel UHD Graphics 730 wins decisively. Intel scores 5988 against AMD's 5358, a delta of 11.8%. This result is notable because the AMD Radeon R7 M445 has 320 shading units, 20 TMUs, and higher FP32 throughput, yet still trails the Intel part by more than ten percent in the OpenCL workload.

Context from the nearest rivals reinforces the gap. The Intel UHD Graphics 730's average score of 5929 places it just 0.4% behind the AMD Radeon HD 8730M (5955), 0.5% behind the NVIDIA Quadro K620M (5957), 0.7% behind the AMD Radeon HD 8750M (5970), and 0.9% behind the NVIDIA Quadro K4000 (5982). Those are all older discrete parts, and the integrated Intel GPU is within a percentage point of them.

The AMD Radeon R7 M445's average score of 5358 sits 0.2% behind the Intel UHD Graphics P630 (5370), 0.7% ahead of the NVIDIA GeForce 840M (5322), 0.8% ahead of the NVIDIA GeForce 930A (5317), and 0.9% ahead of the NVIDIA GeForce GTX 980M (5308). The AMD part is competitive with its immediate neighbors, but the Intel part operates in a higher performance tier altogether.

The pixel rate differential tells a consistent story. Intel's 10.40 GPixel/s is roughly 41% higher than AMD's 7.360 GPixel/s, which aligns with the benchmark lead. The texture rate runs the opposite direction: AMD's 18.40 GTexel/s beats Intel's 15.60 GTexel/s by about 18%. That suggests the AMD part could win texture-bound workloads, but the database records no such head-to-head test. The FP32 compute advantage for AMD (588.8 GFLOPS versus 499.2 GFLOPS) also does not translate into a benchmark win in the recorded OpenCL test.

The Intel part's FP16 throughput of 998.4 GFLOPS is nearly double its FP32 rate, while the AMD part's FP16 and FP32 rates are identical at 588.8 GFLOPS. For applications that leverage packed FP16 math, the Intel architecture provides a clear theoretical advantage. The benchmark data does not isolate FP16 workloads, but the architectural capability is recorded.

In summary, the Intel UHD Graphics 730 wins the only recorded head-to-head test by 11.8%, holds a higher average score, and ranks higher in the overall percentile distribution. The AMD Radeon R7 M445 counters with more shading units, dedicated GDDR5 memory, higher texture rate, and higher FP32 throughput, but none of those advantages appear in the recorded compute benchmark. The database shows Intel as the stronger choice for OpenCL-style workloads, with AMD retaining structural merits for memory-sensitive or texture-heavy use cases.
