AMD Radeon RX Vega M GL vs Intel Arc A770M Comparison

Where Each One Wins

Looking at the recorded benchmark data, this is a lopsided matchup. The Intel Arc A770M takes every single head-to-head win, with the AMD Radeon RX Vega M GL failing to claim a single victory across the shared test suite. The database records two common benchmarks between these parts, and Intel wins both outright.

The AMD Radeon RX Vega M GL does hold a meaningful position in the broader database ranking. Its average benchmark score of 21,153 places it at the 66th percentile of all GPUs, which is actually higher than the Intel Arc A770M's 62nd percentile despite the Intel part winning the direct comparisons. This is a curious situation where the aggregate score, drawn from a wider set of tests, favors AMD, but the direct head-to-head measurements favor Intel by a wide margin.

The Intel Arc A770M is clearly the compute-oriented part here. In Geekbench OpenCL, the Intel GPU scores 89,494 against AMD's 19,549, a delta of -78.2 percent from AMD's perspective. That is not a narrow win; it is a decisive generational gap. Similarly, in Geekbench Vulkan, Intel posts 74,422 against AMD's 22,757, a -69.4 percent delta. For any workload that leans on OpenCL or Vulkan compute, the Arc A770M is the only rational choice between these two.

However, the AMD part has its own niche. The Radeon RX Vega M GL is an integrated-class GPU (IGP) with a 65 W TDP, while the Arc A770M is also listed with an IGP slot width but draws 120 W. For systems where power envelopes are tight and discrete-class cooling is unavailable, the AMD chip's lower power draw is a structural advantage that no benchmark score can fully capture. The database does not include a power efficiency metric, but the raw TDP figures are recorded and they differ by 55 W.

The Intel part dominates in raw throughput metrics as well. Pixel rate is 262.4 GPixel/s versus 32.35 GPixel/s, and texture rate is 524.8 GTexel/s versus 80.88 GTexel/s. FP32 compute is 16.79 TFLOPS versus 2.588 TFLOPS. Every measurable compute resource favors Intel. The AMD part's only relative strength is its smaller footprint and lower power requirement, which matters in compact mobile platforms.

Architecture Differences

The architecture gap here is vast and reflects two very different design philosophies and manufacturing generations. The AMD Radeon RX Vega M GL uses the Polaris 22 chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. The chip packs 5,000 million transistors onto a 208 mm² die, yielding a transistor density of 24.0 million per mm². This is a mature, power-efficient design from 2018, now marked as end-of-life.

The Intel Arc A770M uses the DG2-512 chip built on Xe-HPG architecture, fabricated on a 6 nm process at TSMC. This is a far larger and denser part: 21,700 million transistors on a 406 mm² die, giving a transistor density of 53.4 million per mm². The process node advantage alone is significant, with Intel using a 6 nm node versus AMD's 14 nm node, and the transistor count is over four times higher.

Memory architecture differs fundamentally as well. The AMD part uses 4 GB of HBM2 on a 1024-bit bus, delivering 179.2 GB/s of bandwidth. The Intel part uses 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s. Intel has four times the capacity and nearly three times the bandwidth, though AMD's HBM2 implementation uses a much wider bus to compensate for its lower clocked memory.

The compute resource counts tell a similar story. AMD has 1,280 shading units, 80 texture mapping units, and 32 ROPs. Intel has 4,096 shading units, 256 TMUs, and 128 ROPs. Intel also includes 32 ray tracing cores, a feature AMD's GCN 4.0 architecture lacks entirely. There are no tensor cores on either part, so neither relies on dedicated AI acceleration hardware.

Clock speeds differ as well. AMD's GPU runs at a 931 MHz base and 1011 MHz boost, while Intel runs at 1650 MHz base and 2050 MHz boost. That is a substantial clock advantage for Intel, compounded by its much larger shader count. Memory clocks also differ: AMD's HBM2 runs at 700 MHz with 1400 Mbps effective, while Intel's GDDR6 runs at 2000 MHz with 16 Gbps effective.

API support reflects the architectural gap. AMD supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. Intel supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The move from DirectX 12_0 to 12_2 is significant, as it enables feature-level capabilities like ray tracing and mesh shaders that the older AMD architecture cannot expose.

The bus interface also diverges: AMD uses an integrated graphics processor (IGP) bus, while Intel uses PCIe 4.0 x16. Both are marked as IGP slot width, but Intel's PCIe 4.0 x16 connection allows for system-level data transfer that the AMD part's IGP interface cannot match.

Head-to-Head Benchmarks

The recorded head-to-head data contains only two shared benchmark tests, and the Intel Arc A770M wins both by overwhelming margins.

In Geekbench OpenCL, the Intel Arc A770M scores 89,494, while the AMD Radeon RX Vega M GL scores 19,549. The delta is -78.2 percent, meaning AMD's score is roughly 78 percent lower than Intel's. In practical terms, OpenCL compute workloads that take one second on Intel would take roughly four and a half seconds on AMD. This is not a competitive relationship; it is a demonstration of architectural superiority.

The Geekbench Vulkan test tells a similar story. Intel scores 74,422, AMD scores 22,757, and the delta is -69.4 percent. While slightly less extreme than the OpenCL gap, this still represents a massive performance separation. Vulkan workloads on the AMD part would run at less than a third of Intel's throughput.

The broader database averages reinforce this divide. The AMD part's average benchmark score of 21,153 comes from its two recorded tests, while Intel's average of 18,383 is dragged down by its inclusion of a much wider test suite that includes low-scoring legacy DirectX tests. For example, Intel scores only 56 in Passmark DirectX 10, 69 in DirectX 11, 70 in DirectX 12, and 178 in DirectX 9. These legacy tests pull Intel's average down, even though its modern compute scores are far higher. The AMD part does not have these legacy tests recorded, which flatters its aggregate standing.

In terms of nearest rivals, the AMD part sits closest to the AMD Radeon HD 8970M with an average score of 21,237 and a delta of -0.4 percent, and the NVIDIA RTX A4000 Mobile at 21,379 with a -1.1 percent delta. The Intel part, meanwhile, sits closest to the AMD Radeon RX 460 at 18,373 with a 0.1 percent delta and the AMD FirePro D500 at 18,533 with a -0.8 percent delta. These rival positions confirm that the AMD part punches at a mid-range desktop level, while Intel's aggregate is dragged down by its legacy test scores despite its modern compute dominance.

The only arena where the AMD Radeon RX Vega M GL can claim any advantage is efficiency and physical footprint. At 65 W TDP versus 120 W, it draws nearly half the power. At 208 mm² versus 406 mm², it uses half the die area. For a mobile platform constrained by thermal and power budgets, those differences matter. But for raw performance, the Intel Arc A770M is the clear winner in every recorded benchmark.
