AMD Radeon R5 M320 vs Intel HD Graphics P530 Comparison

Head-to-Head Benchmarks

The two GPUs split their head-to-head benchmark results exactly one win apiece, but the margins tell a more nuanced story. In the Geekbench OpenCL test, the AMD Radeon R5 M320 posts a score of 5051 against the Intel HD Graphics P530’s 4549, a decisive 11% advantage. That is the largest single-performance gap in this comparison, and it places the R5 M320 in a tier that the Intel part cannot reach in compute-heavy workloads. By contrast, the Intel HD Graphics P530 fights back in the Geekbench Vulkan test, scoring 4571 versus the AMD’s 4262, a 6.8% victory. The Intel part’s Vulkan lead is narrower than the AMD’s OpenCL lead, meaning the overall average favors the R5 M320.

Looking at the average benchmark scores, the AMD Radeon R5 M320 sits at 4657, while the Intel HD Graphics P530 trails at 4560. That 97-point gap translates to a roughly 2.1% advantage for AMD in aggregate performance. The percentile rankings reinforce this: the R5 M320 lands in the 27th percentile of all GPUs, while the Intel part sits one point lower at the 26th percentile. Neither GPU is a performance powerhouse, but the data consistently places the AMD part slightly ahead in general compute.

The nearest rival data adds context. The AMD R5 M320’s average score of 4657 exactly matches the AMD Radeon RX 9060 XT 16 GB’s average of 4657, a 0% delta. It also trades blows with the NVIDIA Quadro P400 (4684, -0.6%), the NVIDIA GeForce GTX 970M (4628, +0.6%), and the NVIDIA Quadro M3000M (4621, +0.8%). The Intel HD Graphics P530’s nearest rivals include the AMD Radeon RX 560 (4569, -0.2%), the AMD Radeon R5 M230 (4577, -0.4%), the AMD FirePro W4190M (4505, +1.2%), and the same NVIDIA Quadro M3000M (4621, -1.3%). The overlap in rival sets illustrates that both GPUs operate in the same performance class, with the AMD part edging out the Intel part by a slim margin.

The per-test deltas are worth emphasizing. The 11% OpenCL win for the R5 M320 is more than 1.6 times larger than the 6.8% Vulkan win for the Intel part. In practical terms, if a workload uses OpenCL, the AMD GPU provides a meaningful performance cushion. If the workload uses Vulkan, the Intel GPU closes the gap but does not fully erase the AMD’s overall advantage. Benchmark results indicate that the R5 M320 is the faster GPU on aggregate, but the Intel part has a specific API where it flips the script.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon R5 M320 uses the GCN 1.0 architecture on a 28 nm process node fabricated by TSMC. Its chip, codenamed Jet, contains 690 million transistors on a 56 mm² die, yielding a transistor density of 12.3 million transistors per square millimeter. The Intel HD Graphics P530, by contrast, uses Intel’s Generation 9.0 architecture on a 14 nm+ process node fabricated by Intel. Its chip, Skylake GT2, has a larger die size of 123 mm², though the transistor count and density are not specified in the data. The manufacturing process difference is significant: the Intel part uses a more advanced 14 nm+ node, while the AMD part relies on the older 28 nm node.

Shading resources differ notably. The AMD Radeon R5 M320 packs 320 shading units, 20 texture mapping units, and 8 ROPs. The Intel HD Graphics P530 has 192 shading units, 16 TMUs, and only 3 ROPs. The AMD part leads in every count, with 67% more shading units, 25% more TMUs, and 167% more ROPs. These raw resource differences explain why the AMD part posts higher theoretical pixel and texture rates. The R5 M320 reaches 6.840 GPixel/s and 17.10 GTexel/s, while the Intel part manages 3.000 GPixel/s and 16.00 GTexel/s. The ROP deficit in the Intel part is particularly stark, as it halves the pixel throughput.

Memory architecture diverges completely. The AMD Radeon R5 M320 has dedicated 4 GB of DDR3 memory on a 64-bit bus, delivering 16.00 GB/s of bandwidth. The Intel HD Graphics P530 uses system shared memory, with its bandwidth marked as system dependent. This means the Intel part’s memory performance is contingent on the host system’s RAM configuration, whereas the AMD part has fixed, dedicated bandwidth. The AMD’s memory clock runs at 1000 MHz, translating to 2 Gbps effective, while the Intel part has no dedicated memory clock.

API support differs in key ways. Both GPUs support DirectX 12, but the AMD part implements version 12 (11_1), while the Intel part supports 12 (12_1). OpenGL support is identical at 4.6. Vulkan support favors the Intel part: the HD Graphics P530 supports Vulkan 1.3, whereas the R5 M320 supports Vulkan 1.2.170. The newer Vulkan implementation on the Intel side may explain its Vulkan benchmark victory.

Specification Differences

The two GPUs differ across nearly every specification field. The process node is 28 nm for AMD versus 14 nm+ for Intel. The AMD chip has 690 million transistors on a 56 mm² die; the Intel chip has a 123 mm² die with unspecified transistor count. Transistor density is 12.3M per mm² for AMD, with no figure for Intel. Clock speeds differ substantially: the AMD base clock is 780 MHz with a boost of 855 MHz, while the Intel base clock is 350 MHz with a boost of 1000 MHz. The Intel part has a lower base clock but a higher boost clock, though the AMD part sustains a higher minimum frequency.

Memory configuration is a major split. The AMD Radeon R5 M320 has 4 GB of dedicated DDR3 memory on a 64-bit bus with 16.00 GB/s bandwidth. The Intel HD Graphics P530 shares system memory, with its type, bus width, and bandwidth all marked as system dependent. The AMD’s memory clock is 1000 MHz (2 Gbps effective), while the Intel part has no dedicated memory clock.

Compute resources differ as detailed earlier: 320 shading units, 20 TMUs, and 8 ROPs for AMD versus 192 shading units, 16 TMUs, and 3 ROPs for Intel. Pixel rate is 6.840 GPixel/s versus 3.000 GPixel/s, and texture rate is 17.10 GTexel/s versus 16.00 GTexel/s. FP32 performance is 547.2 GFLOPS for AMD versus 384.0 GFLOPS for Intel. The Intel part has FP16 performance of 768.0 GFLOPS (2:1), while the AMD part has no listed FP16 capability.

Thermal design power is listed only for the Intel part at 15 W; the AMD part has no TDP specified. Both use an IGP slot width, but the bus interface differs: the AMD uses PCIe 3.0 x8, while the Intel uses a Ring Bus. Display outputs are portable device dependent for AMD and motherboard dependent for Intel. DirectX support is 12 (11_1) for AMD versus 12 (12_1) for Intel, and Vulkan support is 1.2.170 versus 1.3. Release dates are close, with AMD launching on May 4, 2015, and Intel on August 31, 2015. Both are end-of-life.

The Verdict

The data points to the AMD Radeon R5 M320 as the faster GPU overall, but the margin is thin and workload-dependent. The AMD part wins the average benchmark score by 97 points (4657 versus 4560) and holds a one-percentile edge (27th versus 26th). Its OpenCL lead of 11% is the largest performance gap in any test, and its raw resource counts are uniformly higher: 320 shading units versus 192, 20 TMUs versus 16, and 8 ROPs versus 3. The AMD also has dedicated 4 GB of DDR3 memory with 16.00 GB/s bandwidth, whereas the Intel part depends on system memory.

However, the Intel HD Graphics P530 has specific advantages. It wins the Vulkan benchmark by 6.8%, supports Vulkan 1.3 versus the AMD’s 1.2.170, and has a higher boost clock at 1000 MHz versus 855 MHz. Its 14 nm+ process node is more advanced than the AMD’s 28 nm, and its 15 W TDP is specified, whereas the AMD part lacks a TDP figure. The Intel part also has FP16 support at 768.0 GFLOPS, which the AMD does not list.

The verdict is clear for general compute: the AMD Radeon R5 M320 is the better choice. Its OpenCL performance is substantially ahead, and its average score confirms superiority. The Intel part is only preferable if the workload is Vulkan-centric or if the lower base clock and system-shared memory are acceptable trade-offs. Neither GPU is competitive in modern gaming, given their 26th and 27th percentile rankings, but within this pairing, AMD takes the performance crown.

Where Each One Wins

The AMD Radeon R5 M320 wins in OpenCL compute workloads. Its Geekbench OpenCL score of 5051 is 11% higher than the Intel’s 4549, and this is the single largest performance margin in the comparison. The AMD also wins in raw pixel throughput, posting 6.840 GPixel/s versus 3.000 GPixel/s, and in texture rate at 17.10 GTexel/s versus 16.00 GTexel/s. Applications that rely on shader count, TMUs, or ROPs will favor the AMD part, as it leads 320 to 192 in shading units, 20 to 16 in TMUs, and 8 to 3 in ROPs. FP32 compute also favors AMD at 547.2 GFLOPS versus 384.0 GFLOPS.

The Intel HD Graphics P530 wins in Vulkan workloads. Its Geekbench Vulkan score of 4571 beats the AMD’s 4262 by 6.8%, and its Vulkan 1.3 API support is newer than the AMD’s 1.2.170. The Intel part also has a higher boost clock at 1000 MHz versus 855 MHz, which may help in bursty, single-threaded tasks. Its FP16 performance of 768.0 GFLOPS is a capability the AMD does not list, making it a better fit for applications that leverage half-precision math. The Intel’s 15 W TDP, while not a performance metric, suggests it fits into tighter power envelopes.

For use cases, the split is straightforward. Choose the AMD Radeon R5 M320 for OpenCL-heavy applications, dedicated memory needs, or any workload that benefits from higher pixel and texture throughput. Choose the Intel HD Graphics P530 for Vulkan-based rendering, systems where shared memory is acceptable, or scenarios where the newer Vulkan API version matters. The AMD wins the overall average, but the Intel wins the API-specific battle that matters most to modern graphics pipelines.
