AMD Radeon RX 7700 vs Intel Arc B770 Comparison

AMD Radeon RX 7700 vs Intel Arc B770 presents a comparison between two contemporary graphics solutions with different design priorities. The data in the database shows a clear split in architectural strategy, raw compute allocation, and memory subsystem configuration. The RX 7700, built on RDNA 3.0, and the Arc B770, built on Xe2-HPG, both target the mainstream performance segment but approach the task from distinct angles. The recorded information allows for a detailed analysis of where each card excels and where the design trade-offs become apparent.

Where Each One Wins

The benchmark data provides a clear picture of the RX 7700’s strengths, as the Arc B770 has no recorded benchmark scores in the database. The RX 7700’s average benchmark score of 15852 places it in the 58th percentile of all GPUs, while the Arc B770 sits at the 50th percentile with no average score recorded. This means the RX 7700 holds the advantage in every measurable category, with its strongest showings in synthetic tests that stress raw computational throughput.

The RX 7700’s PassMark G3D score of 20974 indicates strong overall graphics performance, while its PassMark GPU Compute score of 10963 shows substantial compute capability. The Geekbench OpenCL score of 106028 further confirms the card’s ability to handle general-purpose compute workloads. The 3DMark Steel Nomad DX12 score of 2865 represents modern DirectX 12 gaming performance. The RX 7700 also shows solid legacy API performance with PassMark DirectX 11 score of 186, DirectX 12 score of 96, DirectX 10 score of 92, and DirectX 9 score of 261.

The Arc B770’s advantage, based purely on specifications rather than measured scores, lies in its shading unit count and texture handling. It features 4096 shading units compared to the RX 7700’s 2560, and its 256 TMUs exceed the RX 7700’s 160. The Arc B770’s pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s are higher than the RX 7700’s 236.1 GPixel/s and 393.4 GTexel/s. However, without benchmark scores, these specifications cannot be translated into actual performance wins in the database.

Architecture Differences

The architectural split between these two cards is substantial. The RX 7700 uses the Navi 32 chip with RDNA 3.0 architecture, codenamed Wheat Nas, belonging to the Navi III generation. The Arc B770 uses the BMG-G31 chip with Xe2-HPG architecture, belonging to the Battlemage generation. Both are fabricated on a 5 nm process at TSMC, giving them equal manufacturing technology.

The RX 7700 contains 28,100 million transistors on a 346 mm² die, resulting in a transistor density of 81.2M per mm². The Arc B770’s transistor count is unknown, but its die size is 368 mm², which is larger than the RX 7700’s die. This larger die area for the Arc B770, combined with its higher shading unit count, suggests a different approach to parallel processing.

Clock speeds differ notably. The RX 7700 runs at a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz. The Arc B770 has a higher base clock of 2100 MHz but a slightly lower boost clock of 2400 MHz. Memory clocks also differ: the RX 7700 operates at 2438 MHz with 19.5 Gbps effective speed, while the Arc B770 runs at 2000 MHz with 16 Gbps effective.

The FP32 and FP16 throughput reveal different compute philosophies. The RX 7700 delivers 25.18 TFLOPS for both FP32 and FP16 at a 1:1 ratio, indicating equal handling of both precision types. The Arc B770 delivers 19.66 TFLOPS for FP32 but 39.32 TFLOPS for FP16 at a 2:1 ratio, showing a design that accelerates half-precision workloads significantly. This suggests the Arc B770 may be more suited to workloads that benefit from FP16 throughput, while the RX 7700 provides more balanced compute.

The RX 7700’s percentile of 58 means it performs better than 58% of all GPUs in the database. The Arc B770’s percentile of 50 places it at the median, though this is based on specification similarity rather than measured performance since no benchmark scores are recorded for it.

The Verdict

The database shows the RX 7700 as the card with measured performance data, holding a 58th percentile ranking with an average score of 15852. Its balanced architecture provides 25.18 TFLOPS across both FP32 and FP16, and its memory subsystem delivers 624.1 GB/s of bandwidth. The card’s performance relative to its nearest rivals indicates it sits in a competitive tier, within a few percentage points of the R9 370X, RX 9060, Pro W5500, and RTX 3060 Ti.

The Arc B770 presents a different specification profile with higher shading unit counts, texture units, and pixel throughput. Its 4096 shading units and 256 TMUs suggest a design optimized for geometry-heavy workloads, and its FP16 throughput of 39.32 TFLOPS indicates strong half-precision compute capability. The lack of recorded benchmark scores means its real-world performance cannot be quantified in the database, but its specification advantage in certain areas is clear.

The choice between these cards depends on the priority of measured performance versus specification-based potential. The RX 7700 delivers known quantities: strong DirectX 12 performance, high memory bandwidth, and balanced compute. The Arc B770 offers a larger die, more shading units, and higher pixel rates, but no measured results to confirm how these translate into actual performance. The RX 7700’s 58th percentile ranking and recorded scores provide concrete evidence of its capabilities, while the Arc B770 remains an unverified specification sheet in the database. Users seeking validated performance data would look to the RX 7700, while those interested in the Arc B770’s architectural approach would need to await recorded benchmark results.
