AMD Radeon R7 M445 vs Intel UHD Graphics P630 Comparison

The Intel UHD Graphics P630 and AMD Radeon R7 M445 are both end-of-life mobile graphics solutions, but they represent fundamentally different approaches. The Intel part is a integrated processor graphics unit, while the AMD is a discrete-class IGP. Benchmark data shows they are remarkably close in overall performance, with the AMD R7 M445 holding a slight edge in the single available head-to-head test.

Head-to-Head Benchmarks

The only direct benchmark comparison in the data is the Geekbench OpenCL test. In this test, the AMD Radeon R7 M445 scores 5358 points, while the Intel UHD Graphics P630 scores 5111 points. This gives the AMD part a 4.6% performance advantage in compute workloads. The deltaPct of -4.6% for the Intel part indicates it trails by that margin.

However, the aggregate benchmark picture is even closer. The Intel UHD Graphics P630 has an average benchmark score of 5370 across all tested workloads, which is actually 0.2% higher than the AMD R7 M445's average of 5358. This means that while the AMD wins the OpenCL test, the Intel part edges ahead when considering a broader range of benchmarks. The Intel’s Vulkan score of 5628 is notably strong, though no direct Vulkan comparison exists for the AMD part.

The nearest rival data reinforces this near-parity. The Intel P630’s nearest rival list shows the AMD R7 M445 at a deltaPct of 0.2%, meaning the Intel part is just 0.2% faster on average. Conversely, the AMD’s nearest rival list shows the Intel P630 at a deltaPct of -0.2%, meaning the AMD is 0.2% slower. This is a statistical dead heat, with the two GPUs effectively exchanging blows.

Looking at the wider rival landscape, both parts occupy the same performance tier. The Intel P630 sits 0.8% behind the AMD Radeon R7 M365X and 0.9-1.0% ahead of the NVIDIA GeForce 840M and 930A. The AMD R7 M445 is similarly positioned, being 0.7-0.9% ahead of the same NVIDIA parts and 0.9% behind the NVIDIA GeForce GTX 980M. The data shows no clear winner; it is a coin flip depending on which specific workload is being measured.

Q: Does the Intel UHD Graphics P630 support newer API versions?

A: Yes. The Intel part supports DirectX 12 (12_1) and Vulkan 1.3, while the AMD R7 M445 supports DirectX 12 (12_0) and Vulkan 1.2.170. Both support OpenGL 4.6.

Q: What are the memory specifications for each GPU?

A: The AMD Radeon R7 M445 has 4 GB of dedicated GDDR5 memory on a 64-bit bus with 32.00 GB/s bandwidth. The Intel UHD Graphics P630 uses system shared memory, with a system-dependent bandwidth and bus width.

Q: Which GPU has a higher FP32 compute throughput?

A: The AMD Radeon R7 M445 has a higher FP32 rate of 588.8 GFLOPS compared to the Intel UHD Graphics P630's 460.8 GFLOPS. However, the Intel part has a higher FP16 rate of 921.6 GFLOPS (2:1) versus 588.8 GFLOPS (1:1) for AMD.

Where Each One Wins

The AMD Radeon R7 M445 wins in raw compute throughput. Its FP32 performance of 588.8 GFLOPS is 27.8% higher than the Intel part's 460.8 GFLOPS. It also has a significantly higher pixel rate at 7.360 GPixel/s, versus 3.600 GPixel/s for the Intel, and more ROPs (8 vs 3). This suggests the AMD part is better suited for tasks that demand high fill rates and traditional single-precision compute, such as older game engines or GPU-accelerated physics.

The Intel UHD Graphics P630 wins in texture throughput and API modernity. Its texture rate of 28.80 GTexel/s is 56.5% higher than the AMD's 18.40 GTexel/s, despite having only 24 TMUs versus 20. The Intel part also benefits from a newer process node and higher boost clock, though this doesn't translate to a win in the OpenCL benchmark. For workloads that rely heavily on texture sampling or that leverage newer graphics features, the Intel part is the better choice.

The data also shows the Intel part wins in the aggregate. Its average benchmark score of 5370 is higher, and it has a Vulkan score of 5628, which is a strong result. In scenarios where Vulkan is used, the Intel part is clearly ahead. The AMD part has no Vulkan score recorded, so its performance in that API is unknown. For users who prioritize the latest API support and texture throughput, the Intel P630 is the winner. For those who prioritize raw FP32 compute and pixel fill rate, the AMD R7 M445 is the winner.

Specification Differences

The two GPUs differ in nearly every core specification. The Intel UHD Graphics P630 has 192 shading units, 24 TMUs, and 3 ROPs. The AMD Radeon R7 M445 has 320 shading units, 20 TMUs, and 8 ROPs. The AMD part has 66.7% more shading units and 166.7% more ROPs, but 16.7% fewer TMUs.

Clock speeds also differ substantially. The Intel part has a base clock of 350 MHz and a boost clock of 1200 MHz. The AMD part has a base clock of 780 MHz and a boost clock of 920 MHz. The Intel part has a 30.4% higher boost clock, while the AMD part has a 122.9% higher base clock.

Memory is a major differentiator. The Intel UHD Graphics P630 uses system shared memory with no dedicated VRAM. The AMD Radeon R7 M445 has 4 GB of GDDR5 memory on a 64-bit bus with 32.00 GB/s bandwidth. The AMD's memory clock is 1000 MHz with 4 Gbps effective data rate.

The process node and foundry also differ. The Intel part is built on Intel's 14 nm+++ process, while the AMD part uses TSMC's 28 nm process. The AMD chip, named Meso, has 1,550 million transistors on a 125 mm² die with a transistor density of 12.4M / mm². The Intel part's transistor count and die size are not listed.

The bus interface differs as well. The Intel UHD Graphics P630 uses a Ring Bus, while the AMD Radeon R7 M445 uses PCIe 3.0 x8. The TDP for the Intel part is listed as 15 W, while the AMD part's TDP is not specified.

Architecture Differences

The architectural divide is significant. The Intel UHD Graphics P630 is based on the Generation 9.5 architecture, using the Comet Lake GT2 chip. The AMD Radeon R7 M445 is based on GCN 3.0, using the Meso chip. The Intel part belongs to the HD Graphics-W (Comet Lake) generation, while the AMD part belongs to the Gem System (R7 M400) generation.

The FP16 and FP32 ratios highlight a key architectural difference. The Intel part achieves 921.6 GFLOPS FP16 performance at a 2:1 ratio relative to its FP32 output of 460.8 GFLOPS. The AMD part achieves 588.8 GFLOPS FP16 at a 1:1 ratio, meaning it has no dedicated half-precision acceleration. This makes the Intel architecture more flexible for mixed-precision workloads.

The memory architecture is fundamentally different. The Intel UHD Graphics P630 is an IGP that relies on system shared memory, making its bandwidth "System Dependent." The AMD Radeon R7 M445, while also listed as an IGP slot width, has dedicated 4 GB GDDR5 memory with a fixed 32.00 GB/s bandwidth. This gives the AMD part predictable memory performance, while the Intel part's performance varies with the host system's memory configuration.

The display outputs differ. The Intel part's outputs are "Motherboard Dependent," while the AMD part's are "Portable Device Dependent." This reflects their intended deployment: the Intel part is for desktop or workstation motherboards, while the AMD part is for laptops and portable devices.

The API support also reflects generational differences. The Intel part supports DirectX 12 (12_1) and Vulkan 1.3, while the AMD part supports DirectX 12 (12_0) and Vulkan 1.2.170. Both support OpenGL 4.6. The Intel part's higher DirectX feature level and newer Vulkan version indicate a more modern driver stack.

Finally, the production status and release dates differ. The Intel UHD Graphics P630 was released on May 12, 2020, while the AMD Radeon R7 M445 was released on May 14, 2016. The AMD part lists a predecessor ("Solar System") and successor ("Polaris Mobile"), while the Intel part lists neither. Both are marked as end-of-life.
