Q: Do both cards support the same DirectX version?

A: No. The Intel Arc A310 supports DirectX 12 Ultimate (12_2), while the AMD Radeon HD 7730M supports DirectX 12 (11_1). Both support OpenGL 4.6, but Vulkan support differs (1.4 for Intel, 1.2.170 for AMD).

Architecture Differences

The Intel Arc A310 uses the DG2-128 chip built on Xe-HPG architecture, a 6 nm design from TSMC. The AMD Radeon HD 7730M uses the Chelsea chip based on GCN 1.0, manufactured on TSMC's 28 nm process. The fabrication gap is substantial: 6 nm versus 28 nm, which explains the dramatic differences in transistor density. The Arc A310 packs 7,200 million transistors into a 157 mm² die, while the HD 7730M fits 1,500 million transistors into 123 mm². Density works out to 45.9M per mm² for Intel versus 12.2M per mm² for AMD.

The Arc A310 belongs to the Alchemist generation (Arc 3), succeeding Xe Graphics and preceding Battlemage. The HD 7730M belongs to the London generation (HD 7700M), succeeding Vancouver and preceding Solar System. These are products from different eras, and the architecture reflects that. Xe-HPG is designed for modern gaming features including hardware ray tracing. The Arc A310 has 6 dedicated RT cores. The HD 7730M has no RT cores at all.

Shader resources differ. The Arc A310 has 768 shading units, 32 TMUs, and 16 ROPs. The HD 7730M has 512 shading units, 32 TMUs, and 16 ROPs. Both have the same texture and pixel output pipeline width, but the Intel chip runs far higher clocks: 1750 MHz base and boost versus 575 MHz base and 675 MHz boost for AMD. That clock advantage cascades into every compute metric.

The memory subsystems are fundamentally different. The Arc A310 uses 4 GB of GDDR6 on a 64-bit bus with 124.0 GB/s bandwidth. The HD 7730M uses 2 GB of DDR3 on a 128-bit bus with only 28.80 GB/s. The wider bus helps AMD, but the older, slower memory technology cannot compensate for the bandwidth deficit. The Arc A310 also supports PCIe 4.0 x8, while the HD 7730M uses PCIe 2.0 x16.

Feature support diverges sharply. The Arc A310 supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and has display outputs of 4x mini-DisplayPort 2.0. The HD 7730M supports DirectX 12 (11_1), Vulkan 1.2.170, and its display outputs are listed as "Portable Device Dependent," reflecting its mobile laptop origins. The Arc A310 is a desktop card with a 30 W TDP and no power connectors. The HD 7730M has a 25 W TDP, typical for a mobile part.

The Arc A310 has no tensor cores listed, and the HD 7730M has none either, but the Intel chip does support FP16 at a 2:1 ratio, delivering 5.376 TFLOPS versus 2.688 TFLOPS FP32. The HD 7730M has no FP16 figure recorded.

The Verdict

The data points to a decisive win for the Intel Arc A310. In the only directly comparable benchmark, Geekbench OpenCL, the A310 scores 30,607 versus 6,581 for the HD 7730M, a 365.1% lead. The average benchmark scores tell the same story: 7,550 for Intel versus 6,581 for AMD. The Arc A310 also holds a higher percentile ranking, 40th versus 38th.

The HD 7730M is a mobile-era part from 2012, built on 28 nm with DDR3 memory and GCN 1.0. The Arc A310 is a modern desktop GPU with GDDR6, ray tracing hardware, and a 6 nm process. For anyone choosing between these two, the Arc A310 is the only sensible pick for gaming or compute work. The HD 7730M's only advantages are a wider memory bus and a slightly lower TDP, but neither translates into meaningful performance in the recorded data. The Arc A310 wins the sole head-to-head test, has a higher average score, and brings a much more modern feature set.

That said, the HD 7730M is not without context. It sits at the 38th percentile of all GPUs, which is only 2 points behind the Arc A310's 40th percentile. In the nearest-rival comparison, the HD 7730M is 0.4% ahead of the Intel UHD Graphics P750, while the Arc A310 is 0.1% behind the AMD Radeon R7 250. Both are entry-level performers in their respective generations. But the head-to-head benchmark removes any doubt: the A310 is in a different class.

Head-to-Head Benchmarks

The database records exactly one benchmark where both cards have results: Geekbench OpenCL. The Intel Arc A310 scores 30,607. The AMD Radeon HD 7730M scores 6,581. The delta is 365.1% in favor of Intel. That is not a marginal gap; it is a generational chasm. The A310 processes over four times the OpenCL work of the HD 7730M.

Looking at the broader benchmark suite, the Arc A310 shows a wide spread of results. Its Passmark G3D score is 5,433. Its Passmark GPU Compute score is 2,157. DirectX 9, 10, 11, and 12 scores are 69, 31, 33, and 29 respectively. The G2D score is 625. The HD 7730M has no Passmark results recorded, only the Geekbench OpenCL score. That makes direct comparison limited, but the one shared test is also the most compute-intensive, and Intel dominates it.

The average benchmark score for the Arc A310 is 7,550. The HD 7730M's average is 6,581. That difference of approximately 14.7% is far smaller than the OpenCL gap, which suggests the Intel card's advantage varies heavily by workload. In OpenCL compute, it is enormous. In other areas, the gap narrows considerably. Still, every recorded metric that can be compared favors Intel.

The nearest-rival data adds context. The Arc A310 trails the AMD Radeon R7 250 by 0.1% and the AMD Radeon Pro WX 3100 by 0.4%, while leading the NVIDIA GeForce GTX 1650 by 1% and the AMD Radeon HD 8850M by 1.4%. The HD 7730M leads the Intel UHD Graphics P750 by 0.4% and the NVIDIA GeForce GT 555M by 1.4%, while trailing the AMD Radeon R7 M460 by 0.5% and the NVIDIA GeForce GTX 670M by 1%. These deltas show both cards are competitive within their own performance tiers, but those tiers are far apart.

Where Each One Wins

The Intel Arc A310 wins in compute-heavy workloads. Its OpenCL score of 30,607 dwarfs the HD 7730M's 6,581, which translates to a 365.1% advantage. Its FP32 throughput of 2.688 TFLOPS versus 691.2 GFLOPS for AMD means raw math operations are dramatically faster. The texture rate of 56.00 GTexel/s versus 21.60 GTexel/s doubles the fill rate work Intel can push. Pixel rate of 28.00 GPixel/s versus 10.80 GPixel/s also favors Intel.

For gaming, the Arc A310 is the stronger choice. It supports DirectX 12 Ultimate with ray tracing hardware, 4 GB of GDDR6 memory, and modern Vulkan 1.4 support. The HD 7730M has 2 GB of DDR3, no ray tracing, and only DirectX 12 (11_1). Games that leverage DirectX 12 Ultimate features will simply not run properly on the older AMD card. The A310's memory bandwidth of 124.0 GB/s versus 28.80 GB/s also prevents texture streaming bottlenecks at higher settings.

The AMD Radeon HD 7730M wins in one narrow category only. It has a lower TDP, 25 W versus 30 W for Intel. In a thermally constrained environment where every watt matters, the HD 7730M draws less power. It also has a wider memory bus, 128-bit versus 64-bit, which technically allows more physical memory channels even if the total bandwidth is far lower. For legacy software that expects a 128-bit bus, there could be compatibility considerations, but no benchmark data confirms any advantage.

The HD 7730M also holds up in its own tier. It beats the Intel UHD Graphics P750 by 0.4% and the NVIDIA GeForce GT 555M by 1.4%. It is only 0.5% behind the AMD Radeon R7 M460 and 1% behind the NVIDIA GeForce GTX 670M. For a 2012-era mobile GPU, that is respectable company. But against the Arc A310, there is no contest. The Intel card is faster, newer, and better equipped for modern workloads. The HD 7730M's best hope is legacy compatibility in low-power mobile systems, while the Arc A310 is the clear pick for anyone who needs actual graphics performance today.
