AMD Radeon R8 M445DX vs Intel HD Graphics P530 Comparison

Head-to-Head Benchmarks

The direct comparison between the AMD Radeon R8 M445DX and the Intel HD Graphics P530 is a narrow affair, with only one shared benchmark in the data: Geekbench OpenCL. In that single test, the AMD Radeon R8 M445DX posts a score of 4727, while the Intel HD Graphics P530 trails at 4549. That translates to a 3.9% lead for the AMD part, a modest but definitive margin. The AMD chip’s average benchmark score across all recorded tests is also 4727, while Intel’s average sits at 4560, reflecting the same approximate gap.

The delta between the two is small enough that real-world workloads would likely feel similar, but the numbers are unambiguous: the AMD Radeon R8 M445DX wins the only head-to-head test available. The Intel HD Graphics P530, however, counters with a second benchmark—Geekbench Vulkan—where it scores 4571. That result is not part of a direct head-to-head comparison, but it does show the Intel part has a separate performance profile that may favor certain API workloads. The AMD part has no Vulkan score recorded, so the data cannot confirm whether it would outperform Intel in that specific test.

Context from the nearestRivals list strengthens the picture. The AMD Radeon R8 M445DX sits just 0.5% below the AMD Radeon R5 M335 (4752) and 0.9% above the NVIDIA Quadro P400 (4684). Meanwhile, the Intel HD Graphics P530 is 0.2% below the AMD Radeon RX 560 (4569) and 1.2% above the AMD FirePro W4190M (4505). Both parts occupy a similar performance tier, but the AMD chip’s 3.9% head-to-head win is consistent with its slightly higher percentile ranking (27th vs. 26th among all GPUs). The data suggests a close contest, yet the AMD Radeon R8 M445DX edges ahead in raw compute.

Where Each One Wins

Looking strictly at benchmark results, the AMD Radeon R8 M445DX wins the OpenCL test, which is the only direct comparison available. That gives it a clear, if narrow, victory in general-purpose compute tasks that leverage OpenCL. The Intel HD Graphics P530, on the other hand, has no head-to-head wins—its only recorded victory is the Vulkan score of 4571, which stands alone without a competing AMD result. For users or workloads that rely on Vulkan, the Intel part has demonstrated capability, but the data does not allow for a direct comparison in that API.

The AMD chip’s advantage in OpenCL aligns with its higher shading unit count (320 vs. 192) and its higher clock speeds (base 780 MHz vs. 350 MHz, boost 1021 MHz vs. 1000 MHz). These architectural differences likely contribute to the compute performance edge. The Intel part, however, shows a notable strength in FP16 throughput: 768.0 GFLOPS (2:1 ratio) compared to AMD’s 653.4 GFLOPS (1:1 ratio). That means Intel’s part can process half-precision floating-point data faster, which could matter for certain machine learning or media workloads that use FP16. The AMD part, by contrast, offers higher FP32 performance (653.4 GFLOPS vs. 384.0 GFLOPS), making it more suitable for standard single-precision compute.

In terms of pixel and texture rates, the AMD Radeon R8 M445DX again leads: 8.168 GPixel/s vs. 3.000 GPixel/s, and 20.42 GTexel/s vs. 16.00 GTexel/s. These figures suggest AMD is better equipped for fill-rate-heavy tasks like high-resolution rendering or texture-intensive applications. The Intel part’s lower ROPS count (3 vs. 8) is a clear bottleneck in that regard. So, while the AMD chip wins the compute benchmark outright, the Intel GPU has niche advantages in FP16 and Vulkan, which may translate to specific use cases.

Specification Differences

The two GPUs differ in nearly every core specification. The AMD Radeon R8 M445DX uses a 28 nm process node from TSMC, while the Intel HD Graphics P530 uses a 14 nm+ node from Intel. The AMD chip integrates 1,550 million transistors on a 125 mm² die, while the Intel part’s transistor count is not listed, though its die size is 123 mm². Shading units are starkly different: AMD has 320, Intel has 192. Texture mapping units (TMUs) are 20 vs. 16, and render output units (ROPs) are 8 vs. 3—a significant gap that explains the pixel rate difference.

Clock speeds also diverge: AMD’s base clock is 780 MHz with a boost of 1021 MHz, while Intel’s base is a much lower 350 MHz with a boost of 1000 MHz. The Intel part has a listed TDP of 15 W, whereas the AMD part has no TDP listed. Both use system-shared memory with system-dependent bandwidth, so memory capacity, type, and bus width are identical in being shared. The bus interface differs: AMD uses IGP, while Intel uses Ring Bus. Display outputs are portable-device dependent for AMD and motherboard dependent for Intel.

The feature sets also diverge in API support. The AMD Radeon R8 M445DX supports DirectX 12 (12_0), while the Intel HD Graphics P530 supports DirectX 12 (12_1), indicating a slightly higher feature level. Both support OpenGL 4.6, but Intel’s Vulkan version is 1.3, whereas AMD’s is 1.2.170. The AMD part has a pixel rate of 8.168 GPixel/s and a texture rate of 20.42 GTexel/s; Intel’s are 3.000 GPixel/s and 16.00 GTexel/s, respectively.

Architecture Differences

Beyond raw specs, the two GPUs are built on fundamentally different architectures. The AMD Radeon R8 M445DX is based on the GCN 3.0 architecture, specifically the Meso chip, and belongs to the Gem System Hybrid (Rx M400) generation. The Intel HD Graphics P530 uses the Generation 9.0 architecture, with the Skylake GT2 chip, part of the HD Graphics-W (Skylake) generation. This architectural split explains several behavioral differences: AMD’s GCN 3.0 favors higher FP32 throughput and more shading units, while Intel’s Gen 9.0 emphasizes FP16 compute with a 2:1 ratio.

The process technology is a major differentiator. AMD’s 28 nm node from TSMC is older and less dense, yielding a transistor density of 12.4 million per mm². Intel’s 14 nm+ node, manufactured in-house, is more advanced, though no density figure is listed for it. The foundry difference also matters: TSMC fabricates AMD’s chip, while Intel uses its own fabs. The Intel part’s lower base clock (350 MHz) likely reflects power-saving design for mobile integration, while its boost clock (1000 MHz) nearly matches AMD’s 1021 MHz boost.

The ROP count is the most striking architectural difference: 8 on AMD vs. 3 on Intel. This directly drives the pixel rate disparity (8.168 vs. 3.000 GPixel/s), meaning AMD can process over twice as many pixels per second. The shading unit count (320 vs. 192) gives AMD a clear edge in parallel compute, while Intel’s FP16 capability (768.0 GFLOPS vs. 653.4 GFLOPS) suggests its architecture is tuned for half-precision workloads. The Intel part also supports a newer Vulkan version (1.3 vs. 1.2.170) and a higher DirectX feature level (12_1 vs. 12_0), indicating more modern API integration despite lower raw throughput.

The Verdict

The data points to a clear but narrow winner: the AMD Radeon R8 M445DX. It wins the only direct head-to-head benchmark, boasts higher average scores (4727 vs. 4560), and holds a better percentile rank (27th vs. 26th). Its advantages in shading units, ROPs, pixel rate, texture rate, and FP32 performance make it the stronger choice for general-purpose compute and fill-rate-heavy tasks. The 3.9% lead in OpenCL is not overwhelming, but it is consistent across the broader metric set.

The Intel HD Graphics P530 is not without merit, however. Its FP16 performance (768.0 GFLOPS) exceeds AMD’s, and its Vulkan score (4571) shows it can handle modern graphics APIs. Its lower TDP (15 W) suggests better power efficiency, which could be decisive in battery-constrained systems. For users prioritizing FP16 workloads or Vulkan-based applications, the Intel part may be adequate. But for raw compute power, the AMD Radeon R8 M445DX is the data-backed choice. Neither GPU is a performance leader—both sit below the 30th percentile—but in this matchup, AMD edges out Intel by every measurable metric.
