AMD Radeon RX 7600M vs Intel Arc A770 Comparison

Intel Arc A770 and AMD Radeon RX 7600M represent two very different interpretations of the GPU market, and the benchmark data reflects that clearly. The Arc A770 is a desktop-focused, end-of-life product with a 90th percentile ranking, while the RX 7600M is an active mobile part sitting at the 89th percentile. In the only shared benchmark, the Intel card wins decisively, but that raw score gap tells only part of the story—the architectural and physical differences between these two are vast enough that the "winner" depends entirely on the use case.

The Verdict

The Intel Arc A770 is the obvious choice for anyone building a desktop system that prioritizes raw compute throughput and memory capacity. Its average benchmark score of 68,809 places it 7.9% ahead of the RX 7600M's 63,775, and it sits comfortably at the 90th percentile of all GPUs. The data shows a 71.2% lead in the Geekbench OpenCL head-to-head, which is a massive margin that no amount of driver optimization on the AMD side could realistically close. This card is for users who need maximum FP32 compute, extensive VRAM, and are willing to accommodate a 225W TDP with a 550W suggested PSU.

The AMD Radeon RX 7600M, on the other hand, is the pragmatic pick for mobile or space-constrained systems. It is an active, current-generation product with a 90W TDP and no power connectors—that is a 135W power draw advantage over the Arc A770. If you are selecting a GPU for a laptop or a compact integrated build where thermals and power efficiency are paramount, the RX 7600M is the data-backed choice. Its 89th percentile ranking is nearly identical to the Arc A770's 90th, so performance class is comparable, but the AMD part achieves this in a fraction of the power envelope.

Strictly from the numbers, pick the Arc A770 for desktop performance and the RX 7600M for mobile efficiency. There is no scenario where both cards serve the same purpose well.

Architecture Differences

The Intel Arc A770 uses the DG2-512 chip built on TSMC's 6 nm process, featuring the Xe-HPG architecture from the Alchemist generation. It packs 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The RX 7600M uses the Navi 33 chip, also on TSMC 6 nm, but with RDNA 3.0 architecture from the Navi Mobile generation. AMD's chip contains 13,300 million transistors on a 204 mm² die, resulting in a higher density of 65.2 million per square millimeter.

The compute resources differ substantially. Intel's card has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. AMD's mobile part has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. That is roughly 2.3 times more shading units, TMUs, and ROPs on the Intel side, while AMD has only 12.5% fewer RT cores.

Clock speeds tell a nuanced story. The Arc A770 runs at a 2100 MHz base and 2400 MHz boost, while the RX 7600M has a lower 1500 MHz base but a slightly higher 2410 MHz boost, with a 2070 MHz game clock. Both use GDDR6 memory at 2000 MHz with 16 Gbps effective speed, but the Intel card uses a 256-bit bus with 16 GB and 512.0 GB/s bandwidth, versus AMD's 128-bit bus with 8 GB and 256.0 GB/s bandwidth. The memory subsystem difference is stark: double the capacity, double the bus width, and double the bandwidth.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc A770 has 1x HDMI 2.1 and 3x DisplayPort 2.0 outputs, while the RX 7600M is "Portable Device Dependent" for display outputs.

Head-to-Head Benchmarks

The only directly comparable benchmark is Geekbench OpenCL, and the results are lopsided. The Intel Arc A770 scores 109,175, while the AMD Radeon RX 7600M scores 63,775. That is a deltaPct of 71.2% in favor of Intel. This is not a marginal win—it is a dominant performance gap that reflects the fundamental differences in shading unit count and memory bandwidth.

To put that score in context, the Arc A770's average benchmark score of 68,809 places it between the NVIDIA CMP 90HX (69,000, deltaPct -0.3%) and the AMD Radeon Instinct MI25 (68,562, deltaPct 0.4%). The RX 7600M's 63,775 average sits near the AMD Radeon RX 9060 XT LP (63,830, deltaPct -0.1%) and the NVIDIA CMP 30HX (63,842, deltaPct -0.1%). In other words, the Arc A770 competes with professional-grade compute cards, while the RX 7600M trades blows with entry-level workstation parts.

The Intel card also has a 3DMark Steel Nomad DX12 score of 2,969, which no comparable RX 7600M result exists for in the data. The Vulkan score of 94,284 for the Arc A770 further reinforces its compute versatility, though no direct AMD counterpart is listed.

The wins tally is 1-0 in favor of Intel based on the head-to-head list, but that single benchmark is representative of the overall performance hierarchy.

FAQ

Q: Which GPU has better raw compute performance?

A: The Intel Arc A770 has 19.66 TFLOPS FP32 versus 17.27 TFLOPS for the RX 7600M, and it wins the only shared benchmark (Geekbench OpenCL) by 71.2%. The data is unambiguous.

Q: Can the AMD Radeon RX 7600M match the Intel card's memory bandwidth?

A: No. The Arc A770 has 512.0 GB/s bandwidth with a 256-bit bus and 16 GB VRAM, while the RX 7600M has 256.0 GB/s with a 128-bit bus and 8 GB. That is exactly half in every memory metric.

Q: Is the RX 7600M more power efficient?

A: The data shows the RX 7600M has a 90W TDP with no power connectors, while the Arc A770 has a 225W TDP requiring 1x 6-pin and 1x 8-pin connectors. The AMD part uses 135W less power.

Q: Which card is still in production?

Q: Are these cards suitable for the same types of systems?

A: No. The Arc A770 is a dual-slot desktop card with PCIe 4.0 x16 and discrete display outputs. The RX 7600M is an IGP (integrated graphics processor) with portable device-dependent outputs, designed for laptops.

Where Each One Wins

The Intel Arc A770 wins decisively in any metric involving raw throughput. Its shading unit count of 4,096 versus 1,792, memory bandwidth of 512.0 GB/s versus 256.0 GB/s, and pixel rate of 307.2 GPixel/s versus 154.2 GPixel/s make it the clear choice for compute-heavy workloads like rendering, machine learning inference, or any task that scales with FP32 and memory bandwidth. The texture rate of 614.4 GTexel/s versus 269.9 GTexel/s further cements its dominance in texture-bound scenarios. If you are building a desktop workstation or a high-end gaming rig where power draw is not a constraint, the Arc A770 is the only logical pick from this pair.

The AMD Radeon RX 7600M wins in portability and efficiency. Its 90W TDP versus 225W, lack of power connectors versus the 1x 6-pin + 1x 8-pin requirement, and IGP form factor versus dual-slot make it the only viable option for laptops or compact integrated systems. The higher transistor density of 65.2M / mm² versus 53.4M / mm² suggests AMD uses silicon more efficiently, even if the absolute performance is lower. For users who need 89th percentile performance in a power-constrained environment, the RX 7600M is the data-supported winner.

Neither card wins on every front. The Arc A770 has the higher average benchmark score and a 90th percentile ranking, but the RX 7600M matches that percentile ranking (89th) while drawing 60% less power. The choice between them is a choice between raw capability and practical deployment.
