Architecture Differences

The AMD Radeon RX 9070 GRE is built on the RDNA 4.0 architecture using the Navi 48 chip, fabricated on a 4 nm TSMC process. It contains 53,900 million transistors on a 357 mm² die, resulting in a transistor density of 151.0 million transistors per square millimeter. The Intel Arc B770 uses the Xe2-HPG architecture with the BMG-G31 chip, fabricated on a 5 nm TSMC process with a slightly larger die size of 368 mm². The Arc B770's transistor count is listed as unknown in the database.

The RX 9070 GRE has 3,072 shading units, 192 texture mapping units, and 96 render output units. It also includes 48 ray tracing cores. The Intel Arc B770 has a higher count of shading units at 4,096, along with 256 TMUs and 128 ROPs, but fewer ray tracing cores at 32. The RX 9070 GRE has no tensor cores listed, and neither does the Arc B770.

Clock behavior differs significantly. The RX 9070 GRE has a base clock of 1420 MHz, a boost clock of 2790 MHz, and a game clock of 2220 MHz. The Arc B770 has a higher base clock of 2100 MHz but a lower boost clock of 2400 MHz, with no game clock listed. Memory clocks also differ: the RX 9070 GRE runs at 2250 MHz (18 Gbps effective), while the Arc B770 runs at 2000 MHz (16 Gbps effective).

The compute output shows a notable split. The RX 9070 GRE delivers 34.28 TFLOPS of FP32 performance and the same 34.28 TFLOPS for FP16 (1:1 ratio). The Arc B770 delivers lower FP32 performance at 19.66 TFLOPS but higher FP16 performance at 39.32 TFLOPS (2:1 ratio). This indicates the Intel card uses a different compute path for reduced precision workloads.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 9070 GRE uses a PCIe 5.0 x16 bus interface, while the Arc B770 uses PCIe 4.0 x16. Display outputs are similar, with the RX 9070 GRE offering 1x HDMI 2.1b and 3x DisplayPort 2.1a, and the Arc B770 offering 1x HDMI 2.1a and 3x DisplayPort 2.1.

Where Each One Wins

The available data shows a clear asymmetry between these two cards. The AMD RX 9070 GRE has actual benchmark results recorded in the database, while the Intel Arc B770 has none. This means the RX 9070 GRE can be positioned against real measured performance, while the Arc B770's capabilities remain unquantified.

For the RX 9070 GRE, the recorded benchmarks include a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. Its average benchmark score of 57367 places it in the 87th percentile of all GPUs. The nearest rival data shows the RX 9070 GRE is essentially performance-equivalent to the Intel Arc A580, which scores only 0.7% higher, and slightly behind the AMD RX 5600 OEM (-1.2%), Intel Arc A570M (-1.5%), and AMD RX 6950 XT (-1.8%).

The Intel Arc B770, by contrast, has no benchmark scores, no nearest rivals, and no wins recorded. Its percentile ranking of 50 is a default position, not a measured result. The architecture specifications suggest it is designed for different trade-offs, particularly with its larger 16 GB memory capacity and 512.0 GB/s bandwidth, which could benefit workloads that require large frame buffers or high-resolution textures. The Arc B770's higher FP16 throughput of 39.32 TFLOPS (2:1 ratio) versus the RX 9070 GRE's 34.28 TFLOPS (1:1) indicates potential advantages in compute tasks that use FP16 precision.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the RX 9070 GRE and the Intel Arc B770. The head-to-head benchmark array is empty, and neither card has recorded wins against the other.

The only measurable performance data comes from the RX 9070 GRE's individual benchmarks. In 3DMark Steel Nomad DX12, it scores 5424 points. In Geekbench OpenCL, it scores 109309 points. These scores can be contextualized through the nearest rival data, which shows the RX 9070 GRE trailing the Intel Arc A580 by just 0.7%, the AMD Radeon RX 5600 OEM by 1.2%, the Intel Arc A570M by 1.5%, and the AMD Radeon RX 6950 XT by 1.8%.

The Intel Arc B770 has no recorded benchmark results, no average score, and no rival comparisons. Any attempt to extrapolate its performance from the RX 9070 GRE's rivals would be speculative and unsupported by the database. The Arc B770's specifications, such as its 19.66 TFLOPS FP32 rate, are significantly lower than the RX 9070 GRE's 34.28 TFLOPS, but its higher FP16 output and larger memory bandwidth suggest different performance characteristics depending on the workload.

Without direct measurements, the data cannot confirm which card performs better in any specific test. The RX 9070 GRE has a verified performance footprint; the Arc B770 does not.

The Verdict

The recorded data supports only one conclusion: the AMD Radeon RX 9070 GRE is the only card of the two with measurable performance. Its average benchmark score of 57367 and 87th percentile ranking place it among the higher-performing GPUs in the database. Its nearest rivals all score within 2% of its average, indicating a tight performance cluster. The RX 9070 GRE's launch MSRP is 549 USD.

The Intel Arc B770 has no benchmark results, no average score, and no competitor comparisons. Its 50th percentile ranking is a placeholder, not a measured position. The specifications show a card with more memory (16 GB vs 12 GB), wider memory bus (256 bit vs 192 bit), more shading units (4096 vs 3072), and higher pixel and texture rates. However, its FP32 compute is substantially lower (19.66 TFLOPS vs 34.28 TFLOPS), and its boost clock is 390 MHz lower.

For a buyer choosing between these two based on the database, the RX 9070 GRE has demonstrated performance data that can be compared against other GPUs. The Arc B770's performance is unknown. The RX 9070 GRE's 48 ray tracing cores versus the Arc B770's 32 also gives it an advantage in ray-traced workloads, all else being equal. The Arc B770's larger memory and bandwidth may help in specific scenarios, but without benchmark confirmation, that remains speculative.

The data dictates that the RX 9070 GRE is the safer choice for anyone who wants verified performance. The Arc B770 is an unproven quantity in this database, with specifications that suggest a different design focus but no evidence of actual results. Until the Arc B770 receives benchmark entries, the RX 9070 GRE stands as the only card with a performance record, and its position at the 87th percentile with near-parity to the Arc A580 and RX 5600 OEM gives it a clear, data-backed identity.
