AMD Radeon RX 7600M XT vs Intel Arc B770 Comparison

The Verdict

The data presents a clear split between two very different mobile graphics solutions. The AMD Radeon RX 7600M XT is an established, currently shipping product with a full set of recorded benchmark results. The Intel Arc B770 is a listed product with a future release date and no benchmark scores in the database. This means any direct performance comparison is currently impossible from the recorded data.

For users who need a working GPU today, the RX 7600M XT is the only option with measurable performance. Its average benchmark score of 12710 places it at the 52nd percentile of all GPUs in the database. The nearest rivals confirm its positioning: it sits 0.5% behind the NVIDIA GeForce GTX 670 (average score 12773), 0.7% ahead of the NVIDIA Tesla K20Xm (average score 12625), 0.9% behind the NVIDIA GeForce GTX 590 (average score 12830), and 0.9% behind the AMD Radeon Pro 455 (average score 12831). These are all extremely close margins, indicating the RX 7600M XT occupies a well-defined mid-range performance tier.

The Intel Arc B770 cannot be recommended for purchase based on benchmark data because the database contains no measured scores for it. Its percentile rank of 50 appears to be a default value rather than a measured result, and its average benchmark score is listed as 0. Buyers should treat the Arc B770 as an unverified entry until measurements appear.

Architecture Differences

The two GPUs come from different manufacturers and use different underlying designs. The AMD Radeon RX 7600M XT uses the Navi 33 chip built on RDNA 3.0 architecture, with the internal codename "Hotpink Bonefish." It belongs to the Navi Mobile generation within the RX 7000M series. Its process node is 6 nm at TSMC, with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. Its predecessor is listed as Polaris Mobile.

The Intel Arc B770 uses the BMG-G31 chip built on Xe2-HPG architecture. It belongs to the Battlemage generation within the Arc 7 series. Its process node is 5 nm at TSMC, and the die size is 368 mm². Transistor count is not recorded in the database. Its predecessor is Alchemist.

Both GPUs support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 4.0 x16 bus interface. Neither has tensor cores listed. The AMD chip has 32 ray tracing cores, and the Intel chip also has 32 ray tracing cores, so hardware RT unit counts match.

The RX 7600M XT is an integrated-class mobile part (slot width is listed as IGP) with no power connectors, since it is designed for portable devices. The Arc B770 is a dual-slot card requiring a 1x 6-pin plus 1x 8-pin power connector setup, with a suggested power supply of 550 W. The AMD part draws 120 W TDP, while the Intel part draws 225 W TDP. The display outputs for the AMD part are listed as "Portable Device Dependent," while the Intel part offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

Specification Differences

The two GPUs differ across nearly every core specification. Process node: AMD uses 6 nm, Intel uses 5 nm. Die size: AMD measures 204 mm², Intel measures 368 mm². Transistor count: AMD has 13,300 million, Intel's count is unknown. Transistor density: AMD has 65.2 million per mm², Intel's density is not recorded.

Clock speeds differ in structure. AMD lists base clock at 1280 MHz, boost clock at 2469 MHz, and a game clock of 2023 MHz. Intel lists base clock at 2100 MHz and boost clock at 2400 MHz, with no game clock recorded. Memory clock: AMD runs at 2250 MHz with 18 Gbps effective, Intel runs at 2000 MHz with 16 Gbps effective.

Memory configuration: AMD has 8 GB GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. Intel has 16 GB GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth.

Compute resources: AMD has 2048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores. Intel has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. Pixel rate: AMD delivers 158.0 GPixel/s, Intel delivers 307.2 GPixel/s. Texture rate: AMD delivers 316.0 GTexel/s, Intel delivers 614.4 GTexel/s.

Compute throughput: AMD's FP32 is 20.23 TFLOPS, Intel's is 19.66 TFLOPS. AMD's FP16 is 40.45 TFLOPS (2:1), Intel's is 39.32 TFLOPS (2:1). AMD has a slight edge in raw floating-point throughput despite having half the shading units.

Power and physical design: AMD has 120 W TDP, is listed as IGP slot width, has no power connectors, and no suggested PSU. Intel has 225 W TDP, is dual-slot, requires 1x 6-pin plus 1x 8-pin power, and suggests a 550 W PSU.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two products. The wins counter shows 0 for both sides. The Intel Arc B770 has an empty benchmark array, meaning no measured performance data exists to compare.

The AMD Radeon RX 7600M XT, however, has its own benchmark record. In 3DMark Steel Nomad DX12, it scores 2048. In Geekbench OpenCL, it scores 74869. In Geekbench Vulkan, it scores 27793. PassMark results show DirectX 10 at 76, DirectX 11 at 137, DirectX 12 at 58, DirectX 9 at 175, G2D at 894, G3D at 13907, and GPU compute at 7140. Its average benchmark score across all entries is 12710.

These scores position the RX 7600M XT against its nearest rivals. The 0.5% gap behind the GTX 670 and the 0.7% lead over the Tesla K20Xm show that the AMD part performs in a narrow band around the 12700 score mark. The margins are small enough that individual workloads could flip the ranking. The PassMark G3D score of 13907 is the strongest single result, while the DirectX 12 score of 58 is the weakest, suggesting the GPU is substantially better in older API workloads than in modern DX12 titles.

Without any Intel Arc B770 benchmark data, no meaningful head-to-head performance analysis can be conducted. The specification sheet suggests the Intel part has advantages in memory capacity, bandwidth, pixel rate, and texture rate, while the AMD part has a slight FP32 throughput advantage. But specifications do not translate directly into measured performance, and the database records no evidence for the Arc B770's actual behavior.

Where Each One Wins

The AMD Radeon RX 7600M XT wins in the only category that currently matters: it has verified, recorded performance data. Its average benchmark score of 12710 and its placement at the 52nd percentile of all GPUs give buyers a concrete expectation of its capability. It is a mobile integrated part drawing 120 W, meaning it fits into portable systems without discrete power connections. Its FP32 throughput of 20.23 TFLOPS and FP16 throughput of 40.45 TFLOPS edge out the Intel part's 19.66 and 39.32 TFLOPS respectively, giving it the compute throughput advantage on paper.

The Intel Arc B770 wins on paper in memory and rasterization resources. Its 16 GB memory capacity doubles the AMD part, and its 512.0 GB/s bandwidth is 78% higher than the AMD part's 288.0 GB/s. Its pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s both double the AMD part's respective rates of 158.0 GPixel/s and 316.0 GTexel/s. The 256-bit memory bus and 4096 shading units provide substantially more raw geometry and fill-rate capacity. Its later release date of December 31, 2025 means it represents a newer generation entry, and its predecessor is listed as Alchemist, indicating a direct lineage from Intel's previous discrete GPU effort.

The practical split is straightforward. The RX 7600M XT is the only one of the two with measurable, recorded results, so it is the only one that can be evaluated on evidence. The Arc B770 remains a specification-only entry with no performance verification. Until benchmark entries appear for the Intel part, the database supports no claim that it outperforms the AMD part in any real workload. The AMD card's 52nd percentile ranking and its tight clustering with GTX 670, Tesla K20Xm, GTX 590, and Radeon Pro 455 give it a defined performance identity. The Arc B770 has no such identity in the recorded data.
