AMD Radeon RX 7700 XT vs Intel Arc B770 Comparison

The Verdict

The database positions the AMD Radeon RX 7700 XT as the established, fully measured option, while the Intel Arc B770 appears as a newer entry with its benchmark record still blank. The RX 7700 XT holds an average benchmark score of 22,549 across ten tests, placing it in the 67th percentile of all GPUs. Its nearest rivals show a tight cluster: the NVIDIA GeForce RTX 5060 Mobile is 0.5% ahead, the RTX 2080 is 1.5% ahead, the RTX 4060 Mobile is 0.8% behind, and the AMD Radeon RX 5700 is 1.7% behind. This indicates the RX 7700 XT sits in a competitive band where single-digit percentage swings separate cards.

For the Intel Arc B770, the recorded data shows no benchmark scores, no average, and no rival comparisons. Its percentile rank of 50 is the only positional metric, and that value likely reflects the absence of measurements rather than actual performance. Buyers choosing between these two cards face an asymmetry: the RX 7700 XT has verified results across DirectX 9, 10, 11, 12, OpenCL, Vulkan, and compute workloads, while the Arc B770 has no such data. The verdict from the database is clear: the RX 7700 XT is the only card with demonstrable performance, while the Arc B770 remains an unmeasured variable. The Arc B770 does offer more memory, a wider bus, and a larger die, but without benchmark scores, those specifications cannot be translated into real-world wins.

Architecture Differences

The RX 7700 XT uses the Navi 32 chip built on RDNA 3.0 architecture, produced on a 5 nm process at TSMC. It contains 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The Arc B770 uses the BMG-G31 chip with Xe2-HPG architecture, also on a 5 nm TSMC process, but its transistor count is listed as unknown. Its die size is 368 mm², slightly larger than the Navi 32. The RX 7700 XT belongs to the Navi III generation with the codename Wheat Nas, while the Arc B770 is part of the Battlemage generation, succeeding Alchemist.

Clock behavior differs notably. The RX 7700 XT has a base clock of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz. The Arc B770 runs a higher base of 2100 MHz but a lower boost of 2400 MHz. Memory clocks also diverge: the RX 7700 XT operates at 2250 MHz with 18 Gbps effective, while the Arc B770 runs at 2000 MHz with 16 Gbps effective. Memory capacity favors Intel: 16 GB of GDDR6 on a 256-bit bus delivering 512.0 GB/s, versus 12 GB on a 192-bit bus delivering 432.0 GB/s for AMD.

Compute resources show a split. The Arc B770 has more shading units (4096 vs 3456), more texture mapping units (256 vs 216), and more raster operations units (128 vs 96). It also has fewer ray tracing cores: 32 versus 54. The FP32 throughput tells a different story: the RX 7700 XT delivers 35.17 TFLOPS, while the Arc B770 provides 19.66 TFLOPS. In FP16, the Arc B770 reaches 39.32 TFLOPS with a 2:1 ratio, while the RX 7700 XT matches its FP32 figure at 35.17 TFLOPS with a 1:1 ratio. Pixel and texture rates favor Intel: 307.2 GPixel/s versus 244.2 GPixel/s, and 614.4 GTexel/s versus 549.5 GTexel/s.

Power and physical specs differ as well. The RX 7700 XT has a TDP of 245 W, uses dual-slot cooling with two 8-pin connectors, and suggests a 550 W PSU. The Arc B770 has a lower TDP of 225 W, also dual-slot, but uses one 6-pin and one 8-pin connector, with the same 550 W PSU recommendation. The RX 7700 XT measures 267 mm in length, 135 mm in height, and 50 mm in width; the Arc B770 has no recorded dimensions. Both use PCIe 4.0 x16. Display outputs are similar: both have 1x HDMI 2.1a, but the RX 7700 XT offers 2x DisplayPort 2.1 plus a USB Type-C, while the Arc B770 offers 3x DisplayPort 2.1. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the RX 7700 XT and the Arc B770. The head-to-head array is empty, and neither card records a win in that category. Instead, the available evidence comes from the RX 7700 XT's individual benchmark suite and its rival comparisons.

The RX 7700 XT posts a 3DMark Steel Nomad DX12 score of 3,316. In Geekbench, it scores 138,383 in OpenCL and 46,443 in Vulkan. Passmark results show 119 in DirectX 10, 232 in DirectX 11, 79 in DirectX 12, and 294 in DirectX 9. The G2D score is 1,161, and the G3D score is 22,547. GPU compute reaches 12,912. These numbers establish a baseline for the RX 7700 XT across API generations, with DirectX 9 showing the highest Passmark result and DirectX 12 the lowest, a pattern consistent with older APIs often scaling differently on modern architectures.

The Arc B770 has no recorded benchmark scores, so no direct comparisons can be made. Its only quantitative markers are architectural: higher pixel rate (307.2 GPixel/s), higher texture rate (614.4 GTexel/s), more memory (16 GB), and higher bandwidth (512.0 GB/s). The RX 7700 XT counters with roughly 79% higher FP32 throughput (35.17 TFLOPS vs 19.66 TFLOPS), more ray tracing cores (54 vs 32), and a higher boost clock (2544 MHz vs 2400 MHz). Without benchmark results, the Arc B770's advantages remain theoretical.

Where Each One Wins

The RX 7700 XT wins in every measurable performance category because it is the only card with recorded data. Its average benchmark score of 22,549 places it in the 67th percentile of all GPUs, and its nearest rivals are within a narrow band. The RTX 5060 Mobile is 0.5% faster, the RTX 2080 is 1.5% faster, the RTX 4060 Mobile is 0.8% slower, and the RX 5700 is 1.7% slower. Those deltas are small, meaning the RX 7700 XT competes evenly with a spread of NVIDIA mobile and desktop parts from multiple generations.

The RX 7700 XT also wins on raw FP32 compute, delivering 35.17 TFLOPS versus 19.66 TFLOPS for the Arc B770, a difference of roughly 79%. It has more ray tracing cores (54 vs 32), a higher boost clock (2544 MHz vs 2400 MHz), and a higher memory clock (2250 MHz vs 2000 MHz). Its transistor density of 81.2 million per square millimeter shows a denser design on a smaller die (346 mm² vs 368 mm²), though the Arc B770's total transistor count is unknown.

The Arc B770 wins on memory capacity and bandwidth: 16 GB versus 12 GB, and 512.0 GB/s versus 432.0 GB/s. It also has higher pixel rate (307.2 GPixel/s vs 244.2 GPixel/s), higher texture rate (614.4 GTexel/s vs 549.5 GTexel/s), more shading units (4096 vs 3456), more TMUs (256 vs 216), and more ROPs (128 vs 96). Its base clock is higher at 2100 MHz versus 1435 MHz, and its FP16 throughput is higher at 39.32 TFLOPS versus 35.17 TFLOPS. The Arc B770 also has a lower TDP (225 W vs 245 W) and more DisplayPort outputs (3 vs 2).

The use-case split from the data is straightforward. Applications that rely on FP32 compute, ray tracing, or established benchmark validation favor the RX 7700 XT. Applications that need large frame buffers, high memory bandwidth, higher pixel fill, or higher texture throughput favor the Arc B770 on paper. The Arc B770's advantages are architectural and unverified, while the RX 7700 XT's advantages are measured and confirmed. For a buyer requiring evidence-based performance, the RX 7700 XT is the only option with data. For a buyer prioritizing memory capacity and bandwidth, the Arc B770 offers a compelling specification sheet, but the database currently provides no proof of how those specifications translate into actual scores.
