Intel Arc A550M vs Intel Arc A770 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in favor of the Intel Arc A770 across every shared benchmark. The most lopsided result appears in Geekbench OpenCL, where the A770 scores 109,175 against the A550M's 49,894. That is a 118.8% advantage, meaning the desktop part delivers more than double the compute throughput in this API workload. The margin is not a narrow edge; it is a generational chasm within the same silicon family.

Vulkan results tell a similar story, though with a slightly smaller gap. The A770 posts 94,284 points, while the A550M manages 49,580. The delta here is 90.2%, still a massive lead but reflecting the different optimization paths each GPU takes under Vulkan's explicit control model. Both scores place the A770 in a different competitive tier entirely, and the benchmark database confirms this with a 90th percentile ranking across all GPUs for the A770 versus an 86th percentile for the A550M.

The aggregate benchmark average reinforces the head-to-head pattern. The A770's average sits at 68,809, while the A550M's average lands at 49,737. That translates to a 38.4% overall advantage for the desktop card, a figure that aligns with the raw hardware disparity between the two. Notably, the A770's nearest rivals in the database include the NVIDIA CMP 90HX at 69,000 (a 0.3% deficit for the A770) and the AMD Radeon Pro WX 8200 at 69,870 (a 1.5% gap). The A550M, by contrast, sits alongside the NVIDIA GeForce RTX 5070 Ti at 49,957 (a 0.4% deficit) and the AMD Radeon RX 6900 XT at 50,951 (a 2.4% gap). The A550M actually leads the AMD Radeon RX 6800 XT by 2.6%, but that rival's 48,477 average is still far below the A770's baseline.

What the data does not show is any workload where the A550M claws back ground. With two shared tests and both going to the A770, the wins tally stands at 2-0. There is no scenario in the recorded measurements where the mobile chip's lower power envelope translates into a performance advantage. The A770's higher clock ceiling, larger memory subsystem, and doubled execution resources simply overwhelm the A550M in every measured scenario.

FAQ

Q: How much faster is the Intel Arc A770 than the Intel Arc A550M in Geekbench OpenCL?

A: The A770 scores 109,175 versus the A550M's 49,894, a 118.8% lead. This means the A770 delivers over twice the OpenCL compute performance.

Q: Does the A550M win any benchmark against the A770?

A: No. In the two shared benchmarks (Geekbench OpenCL and Geekbench Vulkan), the A770 wins both. The wins tally is 2 for the A770 and 0 for the A550M.

Q: How does the A770 compare to its nearest rivals in the database?

A: The A770's average benchmark score is 68,809. It trails the NVIDIA CMP 90HX (69,000) by 0.3%, the AMD Radeon Pro WX 8200 (69,870) by 1.5%, and the NVIDIA Quadro P6000 (69,986) by 1.7%. It leads the AMD Radeon Instinct MI25 (68,562) by 0.4%.

Q: What is the A550M's closest competitor according to the data?

A: The A550M's average score is 49,737. Its nearest rival is the NVIDIA GeForce RTX 5070 Ti at 49,957, a 0.4% deficit. It also sits close to the AMD Radeon RX Vega 64 (50,001, a 0.5% deficit) and the AMD Radeon RX 6900 XT (50,951, a 2.4% deficit).

Q: Do both GPUs support the same DirectX and Vulkan feature levels?

A: Yes. Both the A770 and A550M support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The API feature set is identical; the performance difference comes from hardware resources, not software capability.

Q: What is the percentile ranking difference between the two cards?

A: The A770 ranks in the 90th percentile among all GPUs in the database, while the A550M ranks in the 86th percentile. This places the A770 in a higher overall performance tier despite both using the same Xe-HPG architecture.

Architecture Differences

Both the Intel Arc A770 and Intel Arc A550M share the same underlying architecture: Xe-HPG, built on the DG2-512 chip. They are fabricated on TSMC's 6 nm process, with identical transistor counts of 21,700 million and the same die size of 406 mm². The transistor density is also identical at 53.4 million transistors per square millimeter. This means the fundamental silicon is the same; the differences come from how Intel configures and clocks that silicon.

The most significant divergence is in execution resources. The A770 carries 4,096 shading units, 256 texture mapping units, 128 raster output units, and 32 ray tracing cores. The A550M is cut exactly in half: 2,048 shading units, 128 TMUs, 64 ROPs, and 16 RT cores. This halving of every compute block directly explains the performance gap measured in the benchmarks. The A770's FP32 throughput is 19.66 TFLOPS, while the A550M delivers 8.397 TFLOPS. The FP16 figures follow the same 2:1 ratio pattern: 39.32 TFLOPS for the A770 versus 16.79 TFLOPS for the A550M.

Clock speeds add another layer of separation. The A770 runs at a base clock of 2100 MHz and boosts to 2400 MHz. The A550M operates at a much lower 900 MHz base, boosting to 2050 MHz. The A770's higher base clock alone represents a 2.33x advantage before accounting for the doubled execution units. The memory subsystem amplifies the difference further. The A770 uses 16 GB of GDDR6 on a 256-bit bus, running at 2000 MHz (16 Gbps effective), yielding 512.0 GB/s of bandwidth. The A550M is limited to 8 GB of GDDR6 on a 128-bit bus, at 1750 MHz (14 Gbps effective), producing 224.0 GB/s. That is a 2.29x bandwidth advantage for the A770.

Pixel and texture rates tell the same story. The A770 reaches 307.2 GPixel/s and 614.4 GTexel/s, while the A550M manages 131.2 GPixel/s and 262.4 GTexel/s. Both are exact halves, consistent with the ROP and TMU reductions. The power envelope reflects the intended use cases: the A770 is a 225 W dual-slot desktop card requiring a 550 W power supply and a 1x 6-pin plus 1x 8-pin connector setup. The A550M is a 60 W integrated GPU package (IGP) with no power connectors, designed for portable devices where the display outputs are device-dependent. The A770 offers 1x HDMI 2.1 and 3x DisplayPort 2.0 outputs, while the A550M's outputs depend entirely on the host laptop's design.

The Verdict

The benchmark database paints an unambiguous picture: the Intel Arc A770 is the superior performer in every recorded test. For users who need maximum compute throughput, the A770's 19.66 TFLOPS of FP32 performance, 512.0 GB/s of memory bandwidth, and 118.8% OpenCL lead over the A550M make it the clear choice. Its 90th percentile ranking among all GPUs places it in the upper tier of the database, and its average score of 68,809 puts it within striking distance of workstation-class rivals like the NVIDIA Quadro P6000 (69,986) and AMD Radeon Pro WX 8200 (69,870). The A770 is the pick for desktop workloads where power draw of 225 W and dual-slot cooling are acceptable trade-offs.

The Intel Arc A550M, by contrast, targets a different niche entirely. Its 60 W TDP, IGP form factor, and lack of dedicated power connectors make it suitable for portable systems where the A770's desktop footprint is impossible. The A550M's average score of 49,737 still earns an 86th percentile ranking, and it holds its own against the NVIDIA GeForce RTX 5070 Ti (49,957) and the AMD Radeon RX Vega 64 (50,001). For a mobile integrated solution, that level of performance is respectable, but it cannot match the A770's raw output. The 90.2% Vulkan deficit and 118.8% OpenCL deficit are too large to ignore for any workload that demands high frame rates or fast compute.

The choice between these two comes down to the platform. The A770 is for desktops with a 550 W power supply recommendation and PCIe 4.0 x16 connectivity, delivering top-tier performance within the Alchemist generation. The A550M is for laptops and compact devices where the 60 W power budget and integrated design are mandatory constraints. Both share the same architecture, API support, and ray tracing capability, but the A770's doubled execution resources, higher clocks, and 2.29x memory bandwidth make it the definitive performance leader. There is no benchmark scenario in the recorded data where the A550M closes the gap.
