The Verdict

The benchmark data clearly favors the NVIDIA GeForce RTX 5070 SUPER in every recorded performance category. Its 3DMark Steel Nomad DX12 score of 2690 places it at the 18th percentile among all GPUs, with nearest rivals trailing by only 1 to 1.7%. The Arc B770 has no recorded benchmark scores and sits at the 50th percentile, but its complete absence of measured performance data makes direct comparison impossible.

The RTX 5070 SUPER is the choice for users prioritizing raw compute, memory bandwidth, and ray tracing capability. Its FP32 throughput of 32.15 TFLOPS and FP16 throughput of 32.15 TFLOPS (1:1) are both significantly higher than the Arc B770's figures. The NVIDIA card also offers 18 GB of memory versus 16 GB, with 672.0 GB/s bandwidth versus 512.0 GB/s.

The Intel Arc B770 is the choice for users needing more texture units and pixel throughput. It has 256 TMUs versus 200, delivering 614.4 GTexel/s versus 502.4 GTexel/s. Its pixel rate of 307.2 GPixel/s exceeds the NVIDIA card's 201.0 GPixel/s. The Intel card also supports PCIe 4.0 x16, which may be sufficient for older motherboards.

Head-to-Head Benchmarks

The recorded database contains a single benchmark for the RTX 5070 SUPER: 2690 in 3DMark Steel Nomad DX12. The Arc B770 has no benchmark entries, so the head-to-head comparison relies on architectural specifications rather than measured outcomes.

The RTX 5070 SUPER's nearest rivals provide context for its performance tier. The Quadro K1100M scores 2664, which is 1% lower. The GT 1030 scores 2662, 1.1% lower. The Arc Pro B50 scores 2660, also 1.1% lower. The GT 440 trails at 2645, 1.7% behind. These narrow margins indicate the RTX 5070 SUPER sits at the top of a closely packed performance cluster.

The FP32 compute delta is the most pronounced specification gap. The RTX 5070 SUPER's 32.15 TFLOPS represent a 63% advantage over the Arc B770's 19.66 TFLOPS. This translates directly to faster shader processing in most modern workloads. The FP16 figures show a different pattern: the Intel card reaches 39.32 TFLOPS with a 2:1 ratio, which is 22% higher than the NVIDIA card's 32.15 TFLOPS at 1:1, though this only matters for workloads that can exploit packed FP16 operations.

Memory bandwidth shows a 31% advantage for NVIDIA at 672.0 GB/s versus 512.0 GB/s. The RTX 5070 SUPER achieves this with a narrower 192-bit bus but faster GDDR7 memory at 28 Gbps effective, while the Arc B770 uses a wider 256-bit bus with GDDR6 at 16 Gbps effective.

Specification Differences

The RTX 5070 SUPER uses the GB205 chip with Blackwell 2.0 architecture, while the Arc B770 uses the BMG-G31 chip with Xe2-HPG architecture. The NVIDIA card belongs to the GeForce 50-series and GeForce 50 generation, while the Intel card is part of Battlemage (Arc 7).

Clock speeds differ notably. The RTX 5070 SUPER has a base clock of 2325 MHz and boost of 2512 MHz. The Arc B770 operates at 2100 MHz base and 2400 MHz boost. The NVIDIA card's memory runs at 1750 MHz with 28 Gbps effective, while Intel's memory runs at 2000 MHz with 16 Gbps effective.

Memory configuration differs in size, type, and bus width. The RTX 5070 SUPER has 18 GB GDDR7 on a 192-bit bus. The Arc B770 has 16 GB GDDR6 on a 256-bit bus. Bandwidth favors NVIDIA at 672.0 GB/s versus 512.0 GB/s.

The shading unit count heavily favors NVIDIA: 6400 versus 4096. However, Intel has more TMUs (256 versus 200) and more ROPs (128 versus 80). RT core counts are 50 for NVIDIA versus 32 for Intel. The NVIDIA card includes 200 tensor cores; the Intel card lists none.

Pixel rate favors Intel at 307.2 GPixel/s versus 201.0 GPixel/s. Texture rate also favors Intel at 614.4 GTexel/s versus 502.4 GTexel/s.

Power and connectivity differ. The RTX 5070 SUPER has a TDP of 275 W with a single 16-pin connector. The Arc B770 has a TDP of 225 W with 1x 6-pin and 1x 8-pin connectors. The NVIDIA card uses PCIe 5.0 x16, while Intel uses PCIe 4.0 x16.

The RTX 5070 SUPER has recorded dimensions of 245 mm length, 115 mm height, and 40 mm width. The Arc B770's dimensions are unlisted. Both are dual-slot cards. 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.

Architecture Differences

The RTX 5070 SUPER uses Blackwell 2.0 architecture built on a 263 mm² die with 31,100 million transistors. The Arc B770 uses Xe2-HPG architecture on a larger 368 mm² die with an unknown transistor count. Both are fabricated on a 5 nm TSMC process, but the NVIDIA die achieves a density of 118.3M transistors per mm².

The NVIDIA card's Blackwell architecture implements 6400 shading units, 200 TMUs, 80 ROPs, 50 RT cores, and 200 tensor cores. The Intel Xe2-HPG design uses 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores, with no tensor core equivalent listed.

Memory architecture diverges significantly. NVIDIA pairs GDDR7 with a 192-bit interface, while Intel uses GDDR6 with a 256-bit interface. The GDDR7 memory runs at 28 Gbps effective versus 16 Gbps for GDDR6, resulting in higher bandwidth despite the narrower bus.

The FP32 to FP16 ratio differs. The RTX 5070 SUPER delivers 32.15 TFLOPS at both FP32 and FP16, indicating a 1:1 throughput ratio. The Arc B770 delivers 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16, a 2:1 ratio that doubles throughput when using packed operations.

The RTX 5070 SUPER supports PCIe 5.0 x16, doubling the interface bandwidth of the Arc B770's PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The NVIDIA card's production status is listed as Active, while the Intel card has no production status recorded. Both have the same release date in the database.

Where Each One Wins

The RTX 5070 SUPER wins in compute-bound workloads. Its FP32 throughput of 32.15 TFLOPS is 63% higher than the Arc B770's 19.66 TFLOPS. Applications that rely on shader math, physics simulation, or general GPGPU tasks will favor the NVIDIA card. Its 6400 shading units versus 4096 provides a substantial execution resource advantage.

The RTX 5070 SUPER also wins in memory-bound scenarios. Its 672.0 GB/s bandwidth is 31% higher, and its 18 GB capacity exceeds 16 GB. High-resolution texturing, large dataset processing, and memory-intensive rendering benefit from this advantage.

Ray tracing workloads favor the RTX 5070 SUPER with 50 RT cores versus 32. The inclusion of 200 tensor cores gives NVIDIA a dedicated AI acceleration path that the Intel card lacks entirely.

The Arc B770 wins in fill-rate-bound workloads. Its 307.2 GPixel/s pixel rate is 53% higher than the RTX 5070 SUPER's 201.0 GPixel/s. Its 614.4 GTexel/s texture rate is 22% higher than 502.4 GTexel/s. These metrics suggest advantages in rasterization-heavy scenes, particularly at lower resolutions where pixel and texture throughput dominate.

The Arc B770 also wins in FP16-packed workloads. Its 39.32 TFLOPS FP16 output exceeds the RTX 5070 SUPER's 32.15 TFLOPS by 22%, provided the software can utilize the 2:1 packed path.

The Intel card's lower TDP of 225 W versus 275 W indicates less power draw, though the database does not record measured power consumption. Its dual power connectors (1x 6-pin and 1x 8-pin) offer compatibility with older power supplies, while the NVIDIA card requires a single 16-pin connector.

The RTX 5070 SUPER holds the only recorded benchmark score in the database. Its 3DMark Steel Nomad DX12 result of 2690 positions it above its nearest rivals, all of which trail by 1 to 1.7%. The Arc B770 has no recorded benchmark scores, leaving its real-world performance unverified in the database.
