AMD Radeon R7 Graphics vs Intel UHD Graphics P630 Comparison

# Intel UHD Graphics P630 vs AMD Radeon R7 Graphics

The Intel UHD Graphics P630 and AMD Radeon R7 Graphics are both end-of-life integrated graphics solutions, but they represent fundamentally different design philosophies and eras. The Intel part, built on a 14 nm+++ process, delivers an average benchmark score of 5370, while the AMD Radeon R7 Graphics, on a 28 nm node, averages 4998. The Intel chip sits at the 31st percentile of all GPUs, with the AMD part at the 29th percentile, placing both in the lower tier of the performance spectrum. Their head-to-head results show a split decision: Intel wins one test decisively, AMD wins the other by a smaller margin, making the overall choice dependent on workload.

Head-to-Head Benchmarks

The two benchmark tests available — Geekbench OpenCL and Geekbench Vulkan — paint contrasting pictures. In Geekbench OpenCL, the Intel UHD Graphics P630 scores 5111 against the AMD Radeon R7 Graphics' 4015. That is a 27.3% advantage for Intel, a substantial lead in compute-oriented workloads that favor the Intel architecture's higher texture rate and newer feature set. The Intel part's 28.80 GTexel/s texture rate and 460.8 GFLOPS FP32 throughput appear to translate directly into OpenCL performance, where it outperforms the AMD chip by more than a quarter.

However, the Vulkan workload flips the script. The AMD Radeon R7 Graphics scores 5980 in Geekbench Vulkan, while the Intel UHD Graphics P630 trails at 5628. AMD's lead here is 5.9%, a narrower margin than Intel's OpenCL victory but still a clear win. The AMD part's higher pixel rate of 5.760 GPixel/s (versus 3.600 GPixel/s for Intel) and its 384 shading units (double Intel's 192) likely contribute to its Vulkan advantage, even though its texture rate of 17.28 GTexel/s is lower than Intel's.

The wins are split one apiece, but the magnitude of the deltas matters. Intel's OpenCL win is 27.3%, while AMD's Vulkan win is only 5.9%. This asymmetry suggests that the Intel UHD Graphics P630 has a more pronounced strength in OpenCL, while the AMD Radeon R7 Graphics' Vulkan lead is comparatively modest. For users prioritizing OpenCL compute, the Intel part is the clear choice; for Vulkan-centric workloads, the AMD part holds an edge, but not a dominant one.

The nearest rival data corroborates these standings. The Intel UHD Graphics P630's closest competitor is the AMD Radeon R7 M445, which scores 5358 (a 0.2% delta), followed by 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 AMD Radeon R7 Graphics' nearest rivals include the NVIDIA Quadro 4000 at 4979 (0.4%), AMD Radeon R5 M430 at 5018 (-0.4%), NVIDIA GeForce RTX 5060 Ti 16 GB at 4970 (0.6%), and AMD FirePro W4170M at 5034 (-0.7%). Notably, the AMD Radeon R7 Graphics' average score of 4998 places it below its nearest rivals in some cases, while the Intel part's 5370 average sits comfortably within its rival cluster.

The Verdict

The data indicates that the Intel UHD Graphics P630 is the stronger overall performer for compute-heavy applications, specifically those leveraging OpenCL. Its 27.3% advantage in that test is the largest margin between the two, and its average benchmark score of 5370 is 7.4% higher than the AMD Radeon R7 Graphics' 4998. The Intel part also achieves a higher percentile rank (31st versus 29th), suggesting better standing within the broader GPU landscape.

However, the AMD Radeon R7 Graphics is not without merit. Its 5.9% Vulkan lead, while smaller, indicates that users running Vulkan-based applications may see better frame pacing or compute performance. The AMD part's higher pixel rate (5.760 GPixel/s) and double the shading units (384 versus 192) provide architectural headroom that the Intel chip lacks. For graphics workloads that favor pixel throughput or massive parallelism, the AMD part could be preferable.

The choice ultimately depends on the workload. For OpenCL compute, pick the Intel UHD Graphics P630. For Vulkan rendering, the AMD Radeon R7 Graphics is the data-backed choice, though the margin is slim. Neither part is a high-performance solution — both sit below the 31st percentile — but among these two, the Intel part offers the better average score and a more decisive win in one benchmark. The AMD part's single win is narrower, making it the niche pick rather than the all-around option.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The Intel UHD Graphics P630 uses the Generation 9.5 architecture, built on a 14 nm+++ process at Intel's foundry. The chip is codenamed Comet Lake GT2, part of the HD Graphics-W (Comet Lake) generation. This newer process node allows for higher clock speeds — the Intel part boosts to 1200 MHz — and supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The AMD Radeon R7 Graphics, in contrast, uses the GCN 2.0 architecture on a 28 nm process from GlobalFoundries. Its chip, Spectre Lite, belongs to the GCN 2.0 IGP (Kaveri) generation. The AMD part supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, with a slightly older API set.

The process node difference is significant: 14 nm+++ versus 28 nm. Intel's newer node enables higher transistor density and lower power consumption per unit of performance. The AMD part, with its 2,410 million transistors on a 245 mm² die, has a transistor density of 9.8M / mm². The Intel part does not list transistor count or die size in the available data, but its smaller process node suggests a more compact design.

The shader architecture also diverges. The AMD Radeon R7 Graphics has 384 shading units, 24 texture mapping units, and 8 ROPs. The Intel UHD Graphics P630 has 192 shading units, 24 TMUs, and only 3 ROPs. This means AMD has twice the shading units and nearly three times the ROPs, but the same number of TMUs. The AMD part's pixel rate of 5.760 GPixel/s is 60% higher than Intel's 3.600 GPixel/s, while Intel's texture rate of 28.80 GTexel/s is 66.7% higher than AMD's 17.28 GTexel/s. These trade-offs explain the benchmark results: Intel's higher texture rate helps in OpenCL, while AMD's higher pixel rate and shader count help in Vulkan.

Specification Differences

The most striking specification difference is the process node: Intel uses 14 nm+++ while AMD uses 28 nm. This contributes to Intel's lower TDP of 15 W versus AMD's 25 W. The Intel part's base clock is 350 MHz with a boost of 1200 MHz; AMD does not list base or boost clocks. Both use system-shared memory with system-dependent bandwidth, so memory capacity, type, and bus width are identical in concept.

The shading units differ significantly: Intel has 192, AMD has 384. Both have 24 TMUs, but ROPs differ at 3 for Intel and 8 for AMD. Pixel rates are 3.600 GPixel/s for Intel and 5.760 GPixel/s for AMD. Texture rates are 28.80 GTexel/s for Intel and 17.28 GTexel/s for AMD. FP32 performance is 460.8 GFLOPS for Intel and 553.0 GFLOPS for AMD, a 20% advantage for the AMD part. Intel also lists FP16 performance at 921.6 GFLOPS (2:1 ratio), while AMD does not list FP16 at all.

The bus interface differs: Intel uses Ring Bus, while AMD uses IGP. Both have motherboard-dependent display outputs and are IGP (integrated graphics processor) slot width. The API support differs slightly: Intel supports DirectX 12 (12_1) and Vulkan 1.3, while AMD supports DirectX 12 (12_0) and Vulkan 1.2.170. Both support OpenGL 4.6. The AMD part's predecessor is TeraScale 3 IGP and its successor is GCN 3.0 IGP, while Intel lists no predecessor or successor. The AMD part was released on 2014-02-16, while the Intel part came out on 2020-05-12 — a six-year gap that explains the architectural differences.
