Intel Arc A730M vs Intel Arc A770 Comparison

The Verdict

The Intel Arc A770 is the decisive performer in this comparison. Across every recorded benchmark, the desktop card leads the Arc A730M mobile GPU by a substantial margin. The database shows a clean 3-0 sweep in head-to-head tests, with the A770 averaging a 57.4% advantage across the three workloads. For users who need maximum throughput in a desktop system, the A770 is the clear choice.

The Arc A730M, while trailing, is not a weak product in absolute terms. It sits at the 84th percentile among all GPUs, which places it ahead of the majority of recorded hardware. Its average benchmark score of 45,592 is respectable for a mobile part. However, the A770 occupies the 90th percentile with an average score of 68,809, a gap of roughly 51% in average performance. The A770 outperforms its nearest rival, the AMD Radeon Instinct MI25, by 0.4%, while the A730M edges the AMD Radeon Pro 5500 XT by 0.5%. The data suggests the A770 is positioned for demanding desktop workloads, while the A730M serves as a high-end mobile option that cannot match its desktop sibling.

Architecture Differences

Both GPUs share the same fundamental silicon. The Intel Arc A770 and Arc A730M are built on the DG2-512 chip using the Xe-HPG architecture, part of the Alchemist generation. The A770 belongs to the Arc 7 desktop lineup, while the A730M is the Arc 7 Mobile variant. Both use a 6 nm process at TSMC, with 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The core architecture is identical in design philosophy, but the implementation differs significantly in scale.

The A770 packs 4,096 shading units, 256 texture mapping units, 128 raster output units, and 32 ray tracing cores. The A730M reduces these counts to 3,072 shading units, 192 TMUs, 96 ROPs, and 24 RT cores. That is a 25% reduction in shading units and RT cores, and a 25% cut in TMUs and ROPs. The clock speeds diverge further. The A770 runs at a base clock of 2100 MHz and boosts to 2400 MHz. The A730M starts at 1100 MHz base and reaches 2050 MHz boost. The desktop part therefore enjoys both a higher core count and higher clocks, compounding its advantage.

Memory configurations also differ. The A770 uses 16 GB of GDDR6 on a 256-bit bus, with memory running at 2000 MHz (16 Gbps effective), producing 512.0 GB/s of bandwidth. The A730M has 12 GB of GDDR6 on a 192-bit bus, with memory at 1750 MHz (14 Gbps effective), yielding 336.0 GB/s. The A770 offers 33% more memory capacity and 52% more bandwidth. The power envelope reflects these differences: the A770 has a 225 W TDP and requires a 550 W suggested power supply with dual PCIe power connectors (1x 6-pin plus 1x 8-pin). The A730M is rated at 80 W TDP, uses no external power connectors, and is classified as an IGP (integrated graphics package) in slot width terms.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A770 offers display outputs of 1x HDMI 2.1 and 3x DisplayPort 2.0, while the A730M's outputs are portable device dependent, as expected for a mobile part. Both use a PCIe 4.0 x16 bus interface. The A770 was released on October 11, 2022, with a launch MSRP of 329 USD. The A730M has no recorded release date or launch MSRP in the database. The A770 lists Xe Graphics as its predecessor and Battlemage as its successor, while the A730M has no recorded predecessor or successor. Both are marked as end-of-life products.

Head-to-Head Benchmarks

The recorded benchmark data contains three direct comparisons, and the Intel Arc A770 wins all three. The largest gap appears in the 3DMark Steel Nomad DX12 test. The A770 scores 2,969 against the A730M's 1,732, a delta of 71.4%. This test, which stresses modern DirectX 12 rendering workloads, shows the desktop part's advantage in both core count and clock speed translating into a massive lead. The A730M's lower 2050 MHz boost clock and reduced 3,072 shading units simply cannot keep pace with the A770's 2400 MHz boost and 4,096 shading units.

In the Geekbench OpenCL test, the A770 records 109,175 points versus 70,352 for the A730M, a 55.2% advantage. OpenCL performance scales heavily with compute throughput and memory bandwidth, and the A770's 19.66 TFLOPS FP32 and 512.0 GB/s bandwidth dwarf the A730M's 12.60 TFLOPS and 336.0 GB/s. The margin here is slightly smaller than in Steel Nomad, likely because OpenCL workloads also depend on driver scheduling and memory latency, but the outcome is never in doubt.

The Geekbench Vulkan test shows the closest result of the three, though the A770 still wins decisively. The A770 scores 94,284 against 64,693 for the A730M, a 45.7% lead. Vulkan is often more efficient at extracting performance from lower-core-count GPUs, which may explain why the A730M narrows the gap relative to the other tests. Even so, the A770's higher clocks and wider memory bus produce a commanding victory.

Across all three benchmarks, the A770's lead ranges from 45.7% to 71.4%, with an average delta of roughly 57.4%. The A730M's best relative showing is in Vulkan, where its 64,693 score reaches 68.6% of the A770's 94,284. In Steel Nomad, the A730M manages only 58.3% of the A770's score. The pattern is consistent: the desktop part wins every discipline, and the margin grows in tests that stress raw throughput and bandwidth.

The percentile data reinforces this hierarchy. The A770 sits at the 90th percentile among all GPUs, while the A730M sits at the 84th percentile. In the nearest rival lists, the A770's average score of 68,809 puts it within 0.3% of the NVIDIA CMP 90HX (69,000) and 0.4% above the AMD Radeon Instinct MI25 (68,562). The A730M's average of 45,592 places it 1% above the NVIDIA GeForce RTX 5090 Mobile (45,152) and 0.8% below the NVIDIA RTX 5880 Ada Generation (45,972). Both GPUs are competitive within their respective segments, but the A770's segment is simply a higher performance tier. The data leaves no ambiguity: for users choosing between these two, the A770 is the stronger part in every measured category.
