AMD Radeon RX 9070 vs Intel Arc B770 Comparison

Where Each One Wins

The recorded data presents an unusual comparison: the AMD Radeon RX 9070 has a complete set of ten benchmark results, while the Intel Arc B770 has no recorded benchmark scores in the database. This immediately shapes the use-case split. The RX 9070 can be evaluated across DirectX 9, 10, 11, 12, OpenCL, Vulkan, 2D rasterization, 3D rendering, and compute workloads. The Arc B770 currently offers no measurable performance data, meaning its strengths cannot be quantified from the recorded measurements.

For the RX 9070, the benchmark profile shows a card that posts its strongest relative showing in compute-oriented tests. The Geekbench OpenCL score of 131,539 stands far above its Vulkan result of 58,705, indicating substantial raw compute throughput when accessed through general-purpose interfaces. The PassMark G3D score of 25,381 similarly indicates solid conventional rasterization performance. The DirectX 12 score of 74 is notably lower than the DirectX 11 score of 281, which suggests the card's DX12 performance may be constrained by driver overhead or workload characteristics rather than raw hardware capability.

The Arc B770, with its empty benchmark array, cannot claim wins in any recorded test. The database shows zero wins for both cards in head-to-head competition, and zero benchmark entries for the Intel part. This is not a statement about the B770's actual capability, but rather a reflection of the incomplete data record. Until benchmark results are populated, the B770's position in any use-case comparison remains indeterminate.

Architecture Differences

The architectural split between these two cards is substantial. The AMD RX 9070 uses the Navi 48 chip built on RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. The Intel Arc B770 uses the BMG-G31 chip based on Xe2-HPG architecture, fabricated on a 5 nm process, also at TSMC. The process node difference gives AMD a density advantage in principle, though the die sizes tell a more nuanced story.

The RX 9070 die measures 357 mm² and contains 53,900 million transistors, yielding a transistor density of 151.0 million per square millimeter. The B770 die is slightly larger at 368 mm², but its transistor count is listed as unknown in the database, so density cannot be computed. What the recorded data shows is that AMD fits a very high transistor count into a slightly smaller area, which is consistent with the finer 4 nm process.

In terms of compute resources, the two cards take different strategies. The RX 9070 has 3,584 shading units, 224 texture mapping units, 128 ROPs, and 56 ray tracing cores. The B770 has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. Intel's card has 14.3% more shading units and 14.3% more TMUs, but 42.9% fewer ray tracing cores. The ROP count is identical at 128. This suggests AMD concentrates its silicon on ray tracing throughput while Intel allocates more area to conventional shader and texture work.

Clock behavior differs markedly. The RX 9070 has a base clock of 1330 MHz, a boost clock of 2520 MHz, and a game clock of 2070 MHz. The B770 has a base clock of 2100 MHz and a boost clock of 2400 MHz, with no game clock listed. AMD's boost clock is 5% higher, but its base clock is 36.7% lower. Intel runs a much higher baseline frequency, which may indicate different power delivery characteristics or a different approach to sustained load performance.

Memory architecture shows both cards using 16 GB of GDDR6 on a 256 bit bus. The RX 9070, however, runs its memory at 2518 MHz with 20.1 Gbps effective data rate, producing 644.6 GB/s of bandwidth. The B770 runs at 2000 MHz with 16 Gbps effective, producing 512.0 GB/s. AMD's bandwidth advantage is 25.9%, a meaningful gap for texture-heavy and compute workloads.

The floating-point throughput figures reveal a generational philosophy difference. The RX 9070 delivers 36.13 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The B770 delivers 19.66 TFLOPS FP32 but 39.32 TFLOPS FP16, a 2:1 ratio. AMD's FP32 figure is 83.8% higher, while Intel's FP16 figure is 8.8% higher. For applications that can exploit FP16 with 2:1 throughput, the B770 has a theoretical edge; for FP32-centric workloads, the RX 9070 dominates.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two cards. The RX 9070 has ten individual benchmark scores, while the B770 has none. This means every comparison must be framed through the RX 9070's absolute scores and its position relative to other GPUs in the database.

The RX 9070's average benchmark score is 23,877, placing it at the 69th percentile among all GPUs. Its nearest rivals in the database are the AMD Radeon RX 6800S at 24,063 (0.8% ahead of the RX 9070), the NVIDIA GeForce RTX 2080 SUPER at 24,170 (1.2% ahead), the NVIDIA GeForce GTX TITAN Z at 23,736 (0.6% behind), and the NVIDIA GeForce RTX 3080 Mobile at 23,628 (1.1% behind). This cluster of rivals all sit within a 2.3% band, meaning the RX 9070's average performance is essentially tied with upper-midrange GPUs from previous generations.

Looking at the RX 9070's individual benchmarks, the Geekbench OpenCL score of 131,539 is its largest absolute number, but cross-test comparisons are not meaningful due to different scoring scales. Within the PassMark suite, the G3D score of 25,381 dwarfs the DirectX-specific scores, which range from 74 for DX12 up to 343 for DX9. The G2D score of 1,280 indicates modest 2D rasterization performance. The GPU compute score of 14,737 sits between the G2D and G3D results.

The data suggests the RX 9070 performs best in aggregate 3D workloads and OpenCL compute, while its DirectX 12 score of 74 is anomalously low relative to its other results. This pattern may indicate that the card's DX12 path is not yet optimized in the benchmark environment, or that the specific DX12 test used does not align with the card's architectural strengths. The DirectX 11 score of 281 is nearly four times the DX12 score, which is unusual for a modern GPU.

The B770's absence from the benchmark dataset means no head-to-head deltas can be computed. The database shows zero wins for either card, and the average benchmark score for the B770 is 0. This is a data completeness issue, not a performance verdict. The B770's 50th percentile ranking is listed without supporting scores, making it a placeholder rather than an evaluated position.

The Verdict

Based strictly on the recorded data, the AMD Radeon RX 9070 is the only card with measurable performance. Its average benchmark score of 23,877 and 69th percentile ranking place it among established mid-range performers, close to the RX 6800S, RTX 2080 SUPER, and RTX 3080 Mobile. The B770 has no benchmark results, so no performance verdict can be rendered from the database.

For users prioritizing measured performance, the RX 9070's data shows a capable card for 3D rendering and OpenCL compute, with a 25.9% memory bandwidth advantage over the B770's specification and 83.8% higher FP32 throughput. The B770 counters on paper with 14.3% more shading units, 14.3% more TMUs, and 8.8% higher FP16 throughput, but these are unverified by any recorded test.

The RX 9070 also offers a 5% higher boost clock, 75% more ray tracing cores, and a 4 nm process node versus 5 nm. Its launch MSRP is 549 USD. The B770 has no launch MSRP listed and releases later, on 2025-12-31 versus 2025-03-05 for the RX 9070.

For ray tracing workloads, the RX 9070's 56 RT cores versus 32 on the B770 suggest an advantage, though no RT-specific benchmark is recorded. For PCIe bandwidth, the RX 9070's PCIe 5.0 x16 interface outpaces the B770's PCIe 4.0 x16. For power, the two cards are nearly identical at 220 W and 225 W TDP, both recommending a 550 W PSU.

The database currently supports selecting the RX 9070 for any use case requiring verified performance. The B770 remains an unquantified entry, and any claim about its real-world behavior would be speculation not grounded in the recorded measurements.
