Intel Arc A730M vs NVIDIA GeForce RTX 5080 Comparison

The NVIDIA GeForce RTX 5080 and the Intel Arc A730M occupy two entirely different corners of the GPU landscape, and the recorded data reflects that gap on every line. The RTX 5080 is an active, desktop-class Blackwell 2.0 flagship built on TSMC's 5 nm process, while the Arc A730M is an end-of-life mobile Xe-HPG part fabricated on TSMC's 6 nm node. Across the three head-to-head benchmarks in the database, the RTX 5080 wins all three, with margins ranging from 235.3 percent to 398.7 percent. This comparison is therefore less about which card to buy and more about understanding what a full desktop die delivers against a power-frugal integrated mobile design, and where each approach still holds meaning.

Where Each One Wins

The RTX 5080 wins everywhere the two products overlap in measurement. In 3DMark Steel Nomad (DirectX 12), the RTX 5080 scores 8637 against the A730M's 1732, a delta of 398.7 percent. In Geekbench OpenCL it posts 235901 versus 70352, a 235.3 percent advantage, and in Geekbench Vulkan it records 255450 versus 64693, a 294.9 percent lead. The database records three wins for the RTX 5080 and zero for the Arc A730M.

The A730M's case rests entirely on context rather than cross-platform scores. It is an IGP-class mobile design with an 80 W TDP and no external power connectors, whereas the RTX 5080 demands a 360 W TDP, a single 16-pin power connector, and a suggested 750 W power supply. For situations where a discrete desktop card with a 304 mm length and dual-slot footprint simply cannot fit, the A730M exists as a self-contained mobile solution with portable-device-dependent display outputs. Its average benchmark score of 45592 also places it in the 84th percentile against all GPUs in the database, a respectable standing for a mobile part, and its nearest rivals include the NVIDIA GeForce RTX 5090 Mobile and the NVIDIA RTX 5880 Ada Generation, both within roughly one percent of its average score.

It is worth noting the peculiarity of percentile placement: the RTX 5080 sits at the 87th percentile against all GPUs with an average score of 56083, while the A730M sits at the 84th percentile with 45592. The percentile figures are closer than the raw performance gap suggests, reflecting how the database's population weights scores, but the direct measurements leave no ambiguity about which product delivers more compute and graphics throughput.

Architecture Differences

The two GPUs differ in nearly every architectural dimension. The RTX 5080 uses the GB203 chip on the Blackwell 2.0 architecture, manufactured by TSMC on a 5 nm process. It packs 45,600 million transistors into a 378 mm² die, for a transistor density of 120.6M per mm². The Arc A730M uses the DG2-512 chip on the Xe-HPG architecture of the Alchemist generation, also fabricated by TSMC but on a 6 nm process. Its die is physically larger at 406 mm² while holding fewer than half the transistors, 21,700 million, yielding a density of 53.4M per mm². The generational node advantage shows clearly: the RTX 5080 achieves more than double the transistor density on a smaller die.

Resource counts diverge just as sharply. The RTX 5080 fields 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The A730M offers 3072 shading units, 192 TMUs, 96 ROPs, and 24 RT cores, and the database lists no tensor core count for it. That difference in tensor resources underpins the RTX 5080's much stronger positioning for AI and compute workloads, where its FP16 throughput matches its FP32 figure at 56.28 TFLOPS (1:1), while the A730M manages 25.19 TFLOPS FP16 against 12.60 TFLOPS FP32 (2:1).

Clocks and memory tell a similar story. The RTX 5080 runs a 2295 MHz base and 2617 MHz boost clock, with GDDR7 memory at 1875 MHz (30 Gbps effective) on a 256-bit bus delivering 960.0 GB/s of bandwidth. The A730M runs a 1100 MHz base and 2050 MHz boost, with GDDR6 memory at 1750 MHz (14 Gbps effective) on a 192-bit bus delivering 336.0 GB/s. That is a nearly threefold bandwidth advantage for the desktop card. The RTX 5080 carries 16 GB of VRAM versus 12 GB on the A730M.

Feature parity exists at the API level, which is notable: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The interface differs, with the RTX 5080 on PCIe 5.0 x16 and the A730M on PCIe 4.0 x16. The RTX 5080 provides fixed display outputs, one HDMI 2.1b and three DisplayPort 2.1b, while the A730M's outputs are portable-device dependent. The RTX 5080 launched on January 29, 2025, with a launch MSRP of 999 USD, sits in the GeForce 50 generation between the GeForce 40 predecessor and GeForce 60 successor, and remains in active production. The A730M is end-of-life, with no recorded launch date or MSRP in the database.

Head-to-Head Benchmarks

The largest gap appears in 3DMark Steel Nomad under DirectX 12. The RTX 5080 scores 8637 and the A730M scores 1732, a delta of 398.7 percent in NVIDIA's favor. Steel Nomad is a heavyweight modern graphics stress test, and this margin illustrates what the RTX 5080's shading, memory, and bandwidth resources translate to in a demanding raster workload: roughly five times the throughput of the mobile part.

Geekbench Vulkan narrows the gap slightly but not meaningfully. The RTX 5080 records 255450 against the A730M's 64693, a 294.9 percent advantage. Vulkan is an API both cards support at version 1.4, so this result reflects raw GPU capability rather than driver or API feature differences. Even in this closer contest, the desktop card delivers nearly four times the score.

Geekbench OpenCL is the tightest of the three, relatively speaking. Here the RTX 5080 posts 235901 versus 70352 for the A730M, a 235.3 percent delta. OpenCL compute results typically track shader count and clock speed, and the A730M's respectable showing in absolute terms is consistent with its 25.19 TFLOPS FP16 throughput, yet the RTX 5080's 56.28 TFLOPS at both FP32 and FP16, backed by 336 tensor cores, keeps it far ahead.

The RTX 5080's broader benchmark record adds depth the A730M lacks in shared tests. Its Passmark results include a G3D score of 36565, a GPU compute score of 21789, DirectX 9 at 389, DirectX 10 at 208, DirectX 11 at 324, DirectX 12 at 151, and G2D at 1415. Against its own nearest rivals, the RTX 5080 trades blows at the top of its bracket: the AMD Radeon 8060S averages 55757 (0.6 percent behind), the AMD Radeon RX 6750 GRE 12 GB averages 55698 (0.7 percent behind), and the AMD Radeon Pro W5700X averages 54828 (2.3 percent behind), while the AMD Radeon RX 9070 GRE averages 57367 and sits 2.2 percent ahead. The A730M's bracket is similarly tight: the AMD Radeon Pro 5500 XT averages 45384 (0.5 percent behind), the NVIDIA GeForce RTX 5090 Mobile averages 45152 (1 percent behind), the NVIDIA RTX 5880 Ada Generation averages 45972 (0.8 percent ahead), and the NVIDIA RTX A2000 averages 46043 (1 percent ahead).

The Verdict

For any workload where both GPUs are viable options, the data points to the RTX 5080 without qualification. It wins every shared benchmark by a margin of at least 235.3 percent, delivers 960.0 GB/s of memory bandwidth against 336.0 GB/s, provides 84 RT cores and 336 tensor cores against 24 RT cores and no listed tensor count, and remains in active production while the A730M is end-of-life. Users needing a desktop card for demanding DirectX 12 and Vulkan workloads, high-throughput compute, or tensor-accelerated tasks have only one choice between these two.

The A730M's relevance is confined to mobile contexts where its 80 W TDP and integrated form factor are prerequisites rather than compromises. Its 84th percentile standing against the full GPU database, and its proximity in average score to mobile and workstation parts like the RTX 5090 Mobile and RTX 5880 Ada Generation, indicate it was competitive within its own mobile segment. Against a desktop Blackwell flagship, it is simply outclassed: three head-to-head tests, three losses, and no shared measurement where it closes to within even a quarter of the RTX 5080's score.
