Intel Arc B770 vs NVIDIA GeForce RTX 5070 Ti Comparison

Intel Arc B770 vs NVIDIA GeForce RTX 5070 Ti presents a comparison between two very different 16 GB cards from competing architectures. The RTX 5070 Ti carries a substantial performance lead across the board, but the Arc B770 counters with distinct structural advantages. The data shows a clear hierarchy, yet the Arc B770 does not cede every technical category.

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive advantage for the NVIDIA GeForce RTX 5070 Ti. Its average benchmark score of 49957 places it in the 86th percentile of all GPUs, while the Intel Arc B770 sits at the 50th percentile with no recorded benchmark scores in the database. The RTX 5070 Ti delivers 43.94 TFLOPS of FP32 compute performance, which is 124% higher than the Arc B770's 19.66 TFLOPS. This translates directly into compute-heavy workloads where the NVIDIA card effectively doubles the throughput of the Intel offering.

In raw rasterization throughput, the RTX 5070 Ti also leads. Its texture rate of 686.6 GTexel/s exceeds the Arc B770's 614.4 GTexel/s by 11.8%. However, the Arc B770 counters in pixel fill rate. The Intel card reaches 307.2 GPixel/s, which is 30.5% higher than the RTX 5070 Ti's 235.4 GPixel/s. This means the Arc B770 can process more full-screen pixels per second, a factor that can benefit certain resolution-scaling or post-processing scenarios where fragment work dominates.

Memory bandwidth is another major differentiator. The RTX 5070 Ti uses GDDR7 memory on a 256-bit bus to achieve 896.0 GB/s, while the Arc B770 uses GDDR6 on the same 256-bit bus for 512.0 GB/s. The NVIDIA card holds a 75% bandwidth advantage. Both cards have 16 GB of memory, so capacity is equal, but the RTX 5070 Ti can feed its 8960 shading units much faster. The Arc B770 has 4096 shading units, meaning the Intel card operates with less than half the shader count but does so with a higher pixel throughput per shader.

The RTX 5070 Ti shows strong results in specific benchmark tests. In 3DMark Steel Nomad (DX12), it scores 6604. In Geekbench OpenCL it records 212363 points, and in Geekbench Vulkan it hits 225122 points. Passmark results include a G3D score of 32974 and a GPU compute score of 20203. The Arc B770 has no individual benchmark entries in the database, so direct test-by-test comparisons are impossible. The available data instead relies on the aggregate performance metrics and the RTX 5070 Ti's position relative to its nearest rivals.

The nearest rivals list for the RTX 5070 Ti shows a tight cluster. The AMD Radeon RX 6900 XT scores 50951, which is 2% higher. The AMD Radeon RX Vega 64 scores 50001, nearly identical at 0.1% lower. The Intel Arc A550M scores 49737, 0.4% lower. The AMD Radeon RX 6800 XT scores 48477, which is 3.1% lower. The RTX 5070 Ti sits in the middle of this group, statistically close to the RX Vega 64 and Arc A550M, while trailing the RX 6900 XT by a narrow margin. This indicates that the RTX 5070 Ti's performance class is well established, and the Arc B770, with its 50th percentile standing, is not in the same tier.

Architecture Differences

The two GPUs come from completely different design philosophies. The Intel Arc B770 uses the Xe2-HPG architecture on the BMG-G31 chip, part of the Battlemage (Arc 7) generation. The NVIDIA GeForce RTX 5070 Ti uses Blackwell 2.0 on the GB203 chip, part of the GeForce 50 generation. Both are manufactured on a 5 nm process at TSMC, so the underlying transistor technology is identical. The die sizes are close as well: the Arc B770 measures 368 mm², while the RTX 5070 Ti measures 378 mm². The transistor count for the Intel card is listed as unknown, while the RTX 5070 Ti contains 45,600 million transistors with a density of 120.6M per mm².

The compute architectures diverge sharply. The RTX 5070 Ti has 8960 shading units, 280 texture mapping units, and 96 raster output units. The Arc B770 has 4096 shading units, 256 TMUs, and 128 ROPs. NVIDIA pairs its shaders with 70 ray tracing cores and 280 tensor cores. Intel provides 32 ray tracing cores and no tensor cores. This structural difference explains the FP32 gap: the RTX 5070 Ti reaches 43.94 TFLOPS with a 1:1 FP16 ratio, while the Arc B770 reaches 19.66 TFLOPS with a 2:1 FP16 ratio, meaning its FP16 throughput of 39.32 TFLOPS is achieved by doubling up the FP32 hardware.

Memory architecture also differs fundamentally. The Arc B770 uses GDDR6 at 2000 MHz with 16 Gbps effective speed, delivering 512.0 GB/s. The RTX 5070 Ti uses GDDR7 at 1750 MHz with 28 Gbps effective speed, delivering 896.0 GB/s. Both use a 256-bit bus, but the newer GDDR7 standard provides the bandwidth advantage. Clock speeds favor NVIDIA slightly: the RTX 5070 Ti has a base clock of 2295 MHz and a boost of 2452 MHz, while the Arc B770 runs at 2100 MHz base and 2400 MHz boost.

Power and connectivity differ as well. The RTX 5070 Ti has a TDP of 300 W, uses a single 16-pin power connector, and recommends a 700 W PSU. The Arc B770 has a TDP of 225 W, uses one 6-pin and one 8-pin connector, and recommends a 550 W PSU. The RTX 5070 Ti uses PCIe 5.0 x16, while the Arc B770 uses PCIe 4.0 x16. Display outputs are similar: NVIDIA provides 1x HDMI 2.1b and 3x DisplayPort 2.1b, while Intel provides 1x HDMI 2.1a and 3x DisplayPort 2.1. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX 5070 Ti wins in compute-heavy workloads. Its 43.94 TFLOPS FP32 performance, combined with 280 tensor cores, positions it for AI inference, machine learning, and general compute tasks. The 896.0 GB/s memory bandwidth supports large data sets and high-resolution textures without bottlenecking. The 86th percentile ranking confirms its standing among all GPUs, and its average score of 49957 places it in a competitive tier with high-end cards from the previous generation.

The Arc B770 wins in specific rasterization metrics. Its 307.2 GPixel/s pixel rate exceeds the RTX 5070 Ti by 30.5%, which can benefit applications that are fill-rate limited, such as certain 4K rendering passes or fragment-heavy workloads. The 128 ROPs versus 96 ROPs on the NVIDIA card supports this advantage in raw pixel output. The lower TDP of 225 W means the Arc B770 draws less power and can be paired with a 550 W PSU, which gives it an edge in systems with stricter power budgets.

The Arc B770 also holds a transistor density advantage in one respect: its die size of 368 mm² is slightly smaller than the RTX 5070 Ti's 378 mm², yet it packs fewer transistors. This does not translate to a performance win, but it indicates a simpler design. The RTX 5070 Ti's 70 ray tracing cores versus the Arc B770's 32 suggests NVIDIA holds a lead in ray-traced scenes, though no specific ray tracing benchmark scores exist in the database to quantify this.

The Verdict

The data indicates that the NVIDIA GeForce RTX 5070 Ti is the stronger performer for most workloads. Its 43.94 TFLOPS FP32, 896.0 GB/s bandwidth, and 86th percentile ranking place it firmly above the Arc B770, which sits at the 50th percentile with no recorded benchmark scores.

The Arc B770 is not without merit. Its 307.2 GPixel/s pixel rate and 128 ROPs give it a fill-rate advantage, and its 225 W TDP with a 550 W PSU recommendation makes it a lighter load on a system's power delivery. For builders who prioritize pixel throughput or have power supply constraints, the Arc B770 is the practical choice. For anyone seeking peak compute performance, ray tracing capability, or memory bandwidth, the RTX 5070 Ti is the clear pick based on the recorded data.
