Intel Arc B770 vs NVIDIA GeForce RTX 4080 SUPER Comparison

Intel Arc B770 is an upcoming Battlemage generation part built on TSMC’s 5 nm process, while the NVIDIA GeForce RTX 4080 SUPER is an end-of-life Ada Lovelace product that launched in early 2024. The database currently holds no recorded benchmark scores for the Arc B770, so the analysis below relies on the specifications listed for both cards and the measured results available for the RTX 4080 SUPER. The Arc B770 shows a 50th percentile position among all GPUs in the database, while the RTX 4080 SUPER sits at the 86th percentile.

Where Each One Wins

The recorded data gives the RTX 4080 SUPER a clear win in raw compute and memory bandwidth. Its FP32 throughput of 52.22 TFLOPS is more than double the Arc B770’s 19.66 TFLOPS, and its 736.3 GB/s memory bandwidth exceeds the Arc B770’s 512.0 GB/s by a substantial margin. The RTX 4080 SUPER also holds advantages in texture rate, with 816.0 GTexel/s versus 614.4 GTexel/s, and in shading units, with 10240 versus 4096. These figures point to a card that delivers higher peak throughput in GPU-bound tasks that scale with shader count and memory bandwidth.

The Arc B770 wins in several architectural and physical categories. It uses a smaller die at 368 mm² versus 379 mm², and it draws less power, with a 225 W TDP compared to 320 W. The Arc B770 also consumes less system power, with a suggested PSU of 550 W versus 700 W. Its pixel rate is higher at 307.2 GPixel/s compared to 285.6 GPixel/s, which suggests an edge in fill-rate-bound workloads. The Arc B770 also uses a dual-slot cooler with 1x 6-pin plus 1x 8-pin power connectors, whereas the RTX 4080 SUPER is a triple-slot card with a single 16-pin connector. For builders with limited space or older power supplies, the Arc B770’s lower power draw and smaller slot footprint are practical advantages.

Architecture Differences

The Arc B770 uses the Xe2-HPG architecture on the BMG-G31 chip, part of the Battlemage (Arc 7) generation. It is built on a 5 nm process at TSMC with a die size of 368 mm². The transistor count is listed as unknown in the database. The RTX 4080 SUPER uses the Ada Lovelace architecture on the AD103 chip, part of the GeForce 40 generation. It is also built on a 5 nm process at TSMC, with a die size of 379 mm² and 45,900 million transistors. The RTX 4080 SUPER has a transistor density of 121.1M per mm², a figure not available for the Arc B770.

Memory technology differs. The Arc B770 uses 16 GB of GDDR6 on a 256 bit bus, while the RTX 4080 SUPER uses 16 GB of GDDR6X on the same 256 bit bus. The GDDR6X memory runs at 1438 MHz with 23 Gbps effective speed, yielding 736.3 GB/s. The Arc B770’s GDDR6 runs at 2000 MHz with 16 Gbps effective speed, yielding 512.0 GB/s. Both cards have the same memory capacity and bus width, but the RTX 4080 SUPER has roughly 44% more bandwidth.

Compute resources differ significantly. The RTX 4080 SUPER has 10240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. The Arc B770 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores, with no tensor core count listed. The RTX 4080 SUPER’s FP16 throughput is 52.22 TFLOPS with a 1:1 ratio to FP32, while the Arc B770’s FP16 is 39.32 TFLOPS with a 2:1 ratio. This indicates the RTX 4080 SUPER maintains full rate in both FP32 and FP16, while the Arc B770 halves its FP32 rate when computing FP16.

Display outputs also differ. The Arc B770 provides 1x HDMI 2.1a and 3x DisplayPort 2.1. The RTX 4080 SUPER provides 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc B770’s DisplayPort 2.1 output is a newer standard than the RTX 4080 SUPER’s DisplayPort 1.4a, which matters for high refresh rate displays at very high resolutions.

Head-to-Head Benchmarks

The database has no head-to-head benchmark entries for these two cards, and the Arc B770 has no recorded scores in any benchmark. The only measured results available are for the RTX 4080 SUPER. Its 3DMark Steel Nomad DX12 score is 6600. In Geekbench, it scores 219065 in OpenCL and 260075 in Vulkan. Passmark results include 34245 in G3D, 19822 in GPU compute, 1270 in G2D, 381 in DirectX 9, 301 in DirectX 11, 193 in DirectX 10, and 134 in DirectX 12. The average benchmark score across all recorded tests is 54209.

Because the Arc B770 has no recorded measurements, a direct numerical comparison is not possible from the database. The specification data indicates the RTX 4080 SUPER should hold large leads in FP32 compute, memory bandwidth, and texture rate. The Arc B770 counters with a higher pixel rate, lower power draw, and a smaller die. The RTX 4080 SUPER’s percentile rank of 86 versus the Arc B770’s 50 also suggests a higher overall performance tier, though the Arc B770’s rank is based on no recorded benchmarks.

The RTX 4080 SUPER’s nearest rivals in the database are the RTX 4080 with an average score of 54247 and a delta of -0.1%, the AMD Radeon Pro W5700X with 54828 and a delta of -1.1%, the AMD Radeon RX 6750 GRE 12 GB with 55698 and a delta of -2.7%, and the AMD Radeon 8060S with 55757 and a delta of -2.8%. These deltas are small, indicating the RTX 4080 SUPER sits in a tightly clustered performance band around the 54000 to 56000 average score range.

The Verdict

The data supports choosing the RTX 4080 SUPER when peak compute and bandwidth matter most. It doubles the Arc B770’s FP32 throughput, delivers 44% more memory bandwidth, has 2.5 times the shading units, and carries 80 RT cores versus 32. Its 86th percentile rank and measured average score of 54209 confirm a high performance tier. The RTX 4080 SUPER also has a higher boost clock at 2550 MHz versus 2400 MHz, and its GDDR6X memory provides a meaningful bandwidth advantage that benefits high resolution textures and heavy data movement.

The Arc B770 is the better choice when power draw and physical footprint are the priority. Its 225 W TDP and 550 W suggested PSU make it far easier to integrate into existing builds than the 320 W, 700 W RTX 4080 SUPER. The dual-slot cooler and 6-pin plus 8-pin connectors avoid the need for a 16-pin cable. Its 307.2 GPixel/s pixel rate exceeds the RTX 4080 SUPER’s 285.6 GPixel/s, and its DisplayPort 2.1 outputs support newer display connectivity. The lack of recorded benchmarks means its actual performance cannot be confirmed from the database, but the specifications show a card aimed at efficiency and modern display support rather than raw throughput.

For a builder who needs maximum measured performance and is prepared for a larger card and higher power draw, the RTX 4080 SUPER is the clear pick from the recorded data. For a builder who prioritizes lower power consumption, a smaller slot footprint, and newer display outputs, the Arc B770 has the specification advantage.
