AMD Radeon RX 6650M XT vs Intel Arc A770 Comparison

Head-to-Head Benchmarks

The sole direct benchmark comparison available is the Geekbench OpenCL test, and the result is decisively in favor of the Intel Arc A770. The Arc A770 posts a score of 109,175, while the AMD Radeon RX 6650M XT achieves 76,904. This translates to a delta of -29.6% for the AMD part, meaning the Intel GPU is roughly 30% ahead in this specific compute workload. The margin is substantial and consistent with the raw specification gap between the two architectures.

Looking at the broader benchmark landscape, the AMD Radeon RX 6650M XT holds a percentile rank of 91 among all GPUs, with an average benchmark score of 76,904. Its nearest rivals in the database are the NVIDIA GeForce RTX 5090 D (77,712, -1%), the AMD Radeon RX 6850M XT (78,940, -2.6%), and two NVIDIA Tesla P100 variants (79,396 and 79,605, with deltas of -3.1% and -3.4% respectively). The data indicates that the RX 6650M XT sits in a tight cluster of high-end performers, trailing its closest competitors by only a few percentage points.

The Intel Arc A770, by contrast, has a percentile rank of 90, just one point lower than the AMD part, but its average benchmark score across all tests is 68,809. This average is dragged down by including results from other benchmarks beyond the OpenCL test, specifically a 3DMark Steel Nomad DX12 score of 2,969 and a Geekbench Vulkan score of 94,284. In the OpenCL test alone, the Arc A770 is far ahead of the RX 6650M XT, yet its overall average is lower because the 3DMark and Vulkan results are significantly below the OpenCL figure.

The nearest rivals for the Intel Arc A770 include the NVIDIA CMP 90HX (69,000, -0.3%), the AMD Radeon Instinct MI25 (68,562, +0.4%), the AMD Radeon Pro WX 8200 (69,870, -1.5%), and the NVIDIA Quadro P6000 (69,986, -1.7%). This positions the Arc A770 in a different performance tier than the RX 6650M XT, even though their percentile ranks are nearly identical. The Arc A770's average is roughly 10% lower than the RX 6650M XT's average, but the head-to-head OpenCL result tells the opposite story.

The discrepancy between the head-to-head result and the average scores highlights the importance of workload-specific testing. In raw OpenCL compute, the Intel part is clearly superior, but the AMD part appears more consistent across a broader range of benchmarks. The data shows that the RX 6650M XT's single benchmark result is its average, while the Arc A770's average is a composite of three very different tests. This means the delta between the two in the head-to-head is not necessarily representative of their overall performance relationship.

One additional observation: the Arc A770's Vulkan score of 94,284 is notably lower than its OpenCL score of 109,175, indicating that its performance varies significantly by API. The RX 6650M XT has no Vulkan score listed, so no direct comparison is possible there. However, the fact that the Intel GPU wins the OpenCL test by 29.6% and still has a lower average suggests the AMD part may hold advantages in other untested workloads.

The Verdict

From the data, the Intel Arc A770 is the clear winner in the only direct head-to-head benchmark available. Its Geekbench OpenCL score of 109,175 versus 76,904 for the AMD Radeon RX 6650M XT represents a 29.6% advantage, which is a substantial margin in compute-oriented tasks. Anyone prioritizing raw OpenCL performance should select the Intel Arc A770 based on this evidence.

However, the verdict is not one-sided. The AMD Radeon RX 6650M XT has a higher average benchmark score (76,904) than the Intel Arc A770 (68,809) when considering all listed results. The RX 6650M XT also holds a slightly higher percentile rank (91 versus 90). This suggests that, outside of the specific OpenCL test, the AMD part may deliver more balanced performance across diverse workloads. The data does not include other direct head-to-head tests, so this inference is drawn from the aggregate scores.

For users who need a mobile solution, the RX 6650M XT is an integrated graphics processor (IGP) with a 120 W TDP and no power connectors, making it suitable for laptops. The Arc A770, in contrast, is a dual-slot desktop card with a 225 W TDP, requiring a 1x 6-pin + 1x 8-pin power connection and a 550 W suggested PSU. The form factor and power requirements alone dictate different use cases.

The launch MSRP for the Intel Arc A770 is 329 USD. The AMD Radeon RX 6650M XT has no launch MSRP listed. The data provides no pricing information for the AMD part, so any cost comparison is impossible from the provided facts.

Ultimately, the choice depends on workload and system constraints. The Intel Arc A770 is the better performer in OpenCL compute and offers double the memory bandwidth and capacity. The AMD Radeon RX 6650M XT, with its lower power draw and IGP form factor, is designed for mobility and likely fits into systems where a discrete dual-slot GPU is not an option. The data does not support a universal recommendation; it supports a workload-specific one.

Specification Differences

The two GPUs differ in nearly every major specification. The AMD Radeon RX 6650M XT uses the Navi 23 chip with 11,060 million transistors on a 237 mm² die, while the Intel Arc A770 uses the DG2-512 chip with 21,700 million transistors on a 406 mm² die. The process nodes also differ: 7 nm for AMD versus 6 nm for Intel, both fabricated by TSMC. Transistor density is higher on the Intel part at 53.4M / mm² compared to 46.7M / mm².

Clock speeds are similar in boost (2416 MHz for AMD versus 2400 MHz for Intel), but the base clocks differ (2068 MHz versus 2100 MHz). The AMD part also lists a game clock of 2162 MHz, while the Intel part has no game clock specified. Memory configurations diverge sharply: 8 GB versus 16 GB, 128-bit versus 256-bit bus, and 256.0 GB/s versus 512.0 GB/s bandwidth.

Compute resources are doubled on the Intel side: 4096 shading units versus 2048, 256 TMUs versus 128, and 128 ROPs versus 64. Both have 32 ray tracing cores. The pixel rate is 307.2 GPixel/s for Intel versus 154.6 GPixel/s for AMD, and texture rates are 614.4 GTexel/s versus 309.2 GTexel/s. FP32 performance is 19.66 TFLOPS versus 9.896 TFLOPS, and FP16 is 39.32 TFLOPS versus 19.79 TFLOPS.

Power and physical specs differ significantly. The AMD part is an IGP with 120 W TDP and no power connectors, while the Intel part is a dual-slot card with 225 W TDP and 1x 6-pin + 1x 8-pin connectors. The suggested PSU for the Intel card is 550 W. The bus interface is PCIe 4.0 x8 for AMD and PCIe 4.0 x16 for Intel. Display outputs are portable-device-dependent for AMD, while Intel provides 1x HDMI 2.1 and 3x DisplayPort 2.0.

Architecture Differences

The architectural foundations are entirely different. The AMD Radeon RX 6650M XT is built on RDNA 2.0, part of the "Navi Mobile (RX 6000M)" generation. The Intel Arc A770 uses Xe-HPG architecture, from the "Alchemist (Arc 7)" generation. The AMD chip is codenamed Navi 23, while the Intel chip is DG2-512.

The AMD part's predecessor is Polaris Mobile, and it has no successor listed. The Intel part's predecessor is Xe Graphics, and its successor is Battlemage. This indicates the Intel architecture is part of a newer, evolving line, while the AMD architecture is a mature, end-of-life design.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part has no tensor cores listed, and neither does the Intel part. The ray tracing core count is identical at 32, but the underlying implementations differ due to the distinct architectures.

The AMD RDNA 2.0 design emphasizes efficiency, as evidenced by its 120 W TDP and IGP form factor. The Intel Xe-HPG design prioritizes raw throughput, with double the shading units, TMUs, and ROPs, resulting in a 225 W TDP. The transistor count difference — 21,700 million versus 11,060 million — reflects the Intel chip's larger, more complex design.

The memory subsystem also reflects architectural choices. The Intel part uses a 256-bit bus to achieve 512.0 GB/s, while the AMD part uses a 128-bit bus for 256.0 GB/s. The Intel part's 16 GB capacity doubles the AMD part's 8 GB, which is significant for large datasets or high-resolution textures. The release dates differ by roughly nine months, with AMD launching on January 3, 2022, and Intel on October 11, 2022.
