AMD Radeon R5 M335 vs Intel UHD Graphics P630 Comparison

Where Each One Wins

The benchmark data splits cleanly in favor of Intel UHD Graphics P630, which takes both recorded head-to-head tests. The Intel part wins in Geekbench OpenCL with a 7.7% margin and in Geekbench Vulkan with a larger 18.3% margin. For users running OpenCL workloads, the Intel solution holds a modest but consistent advantage; for Vulkan-based applications, that advantage widens substantially, making the Intel part the stronger choice for modern graphics APIs.

AMD Radeon R5 M335 does not win either recorded benchmark. Its closest competition in the database includes AMD Radeon R8 M445DX, which sits 0.5% ahead, and AMD Radeon R5 M255, which trails by 0.7%. The R5 M335 occupies the 28th percentile among all GPUs, while the Intel UHD Graphics P630 sits at the 31st percentile, indicating a slight overall positioning advantage for the Intel part. In practical terms, the AMD solution is better suited to scenarios where its dedicated 2 GB VRAM and higher raw pixel throughput matter, such as legacy DirectX 11 workloads that favor memory bandwidth and fillrate over API-level compute performance. The Intel part, by contrast, leverages its newer architecture and superior Vulkan implementation for tasks that stress modern graphics interfaces.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. Intel UHD Graphics P630 uses the Generation 9.5 architecture, built on Intel's 14 nm+++ process with a Comet Lake GT2 chip. The AMD Radeon R5 M335 uses the older GCN 1.0 architecture, manufactured on TSMC's 28 nm process with the Exo chip. The process node difference alone, 14 nm+++ versus 28 nm, explains much of the efficiency and clock behavior gap.

Transistor counts and die sizes reinforce the architectural gap. AMD's chip packs 690 million transistors into a 56 mm² die, yielding a transistor density of 12.3 million per square millimeter. Intel does not report transistor count or die size in the database, but its integrated design shares the CPU package, which changes the thermal and power context entirely. The AMD part is a discrete mobile GPU with 320 shading units, 20 texture mapping units, and 8 ROPs. The Intel part offers 192 shading units, 24 TMUs, and only 3 ROPs. Despite fewer shading units, the Intel GPU achieves a higher texture rate of 28.80 GTexel/s versus AMD's 20.60 GTexel/s, thanks to its higher TMU count and clock behavior.

Memory architecture differs sharply. Intel UHD Graphics P630 uses system shared memory with a system-dependent bandwidth figure, meaning performance scales with the host platform's RAM configuration. AMD Radeon R5 M335 has 2 GB of dedicated DDR3 memory on a 64-bit bus, delivering 14.40 GB/s bandwidth and 1800 Mbps effective memory speed. This dedicated memory gives the AMD part a predictable performance floor, while the Intel part's shared memory approach can vary widely depending on the laptop's memory setup.

API support also separates the two. Intel supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. AMD supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The Intel part's newer Vulkan version directly correlates with its 18.3% win in the Geekbench Vulkan test.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows Intel UHD Graphics P630 scoring 5111 against AMD Radeon R5 M335's 4745, a 7.7% advantage. This margin reflects the Intel part's higher texture rate and newer architecture, despite the AMD part's larger shading unit count. The AMD GPU's 320 shaders versus Intel's 192 does not translate into a compute win, likely because GCN 1.0's compute efficiency lags Intel's Generation 9.5 design in OpenCL workloads.

The Geekbench Vulkan test produces a more decisive result. Intel scores 5628, AMD scores 4758, giving Intel an 18.3% lead. This is the largest gap in the comparison and directly tied to API maturity: Intel's Vulkan 1.3 driver stack outperforms AMD's Vulkan 1.2.170 implementation on this older GCN chip. For any application leveraging Vulkan, the Intel part is clearly the superior option.

The average benchmark scores tell the same story. Intel UHD Graphics P630 averages 5370 across its recorded tests, while AMD Radeon R5 M335 averages 4752, a difference of 618 points. The Intel part's nearest rivals include AMD Radeon R7 M445 (5358, 0.2% ahead), AMD Radeon R7 M365X (5416, 0.8% behind), NVIDIA GeForce 840M (5322, 0.9% ahead), and NVIDIA GeForce 930A (5317, 1% ahead). The AMD R5 M335's nearest rivals include AMD Radeon R8 M445DX (4727, 0.5% ahead), AMD Radeon R5 M255 (4788, 0.7% behind), NVIDIA GeForce RTX 3080 12 GB (4791, 0.8% behind), and NVIDIA Quadro P400 (4684, 1.5% ahead).

Specification Differences

The two GPUs differ across nearly every measurable specification. Intel UHD Graphics P630 runs at a base clock of 350 MHz with a boost clock of 1200 MHz, while AMD Radeon R5 M335 lists no base or boost clock in the database, only a memory clock of 900 MHz with 1800 Mbps effective. The Intel part's boost clock of 1200 MHz is the only core frequency available for comparison.

Shading units favor AMD at 320 versus Intel's 192. Texture mapping units favor Intel at 24 versus AMD's 20. Raster output units favor AMD at 8 versus Intel's 3. Pixel rate favors AMD at 8.240 GPixel/s versus Intel's 3.600 GPixel/s. Texture rate favors Intel at 28.80 GTexel/s versus AMD's 20.60 GTexel/s. FP32 compute favors AMD at 659.2 GFLOPS versus Intel's 460.8 GFLOPS. FP16 compute is only listed for Intel at 921.6 GFLOPS (2:1); AMD has no recorded FP16 figure.

Memory configuration is a major differentiator. AMD has 2 GB of DDR3 on a 64-bit bus with 14.40 GB/s bandwidth. Intel uses system shared memory with system-dependent bandwidth. Power draw is only listed for Intel at 15 W; AMD's TDP is not recorded. The Intel part is an IGP with a ring bus interface, while AMD is a discrete chip using PCIe 3.0 x8. Display outputs are motherboard dependent for Intel and portable device dependent for AMD. Intel supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3; AMD supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170.

Release dates differ by nearly five years. Intel launched on May 12, 2020; AMD launched on October 20, 2015. Both are end-of-life products. AMD's predecessor is Solar System and its successor is Polaris Mobile; Intel lists no predecessor or successor.
