Architecture Differences

The Intel Arc B770 and NVIDIA GeForce RTX 5080 represent two fundamentally different architectural approaches. The Arc B770 uses Intel's Xe2-HPG architecture on the BMG-G31 chip, part of the Battlemage (Arc 7) generation. The RTX 5080 uses NVIDIA's Blackwell 2.0 architecture on the GB203 chip, belonging to the GeForce 50-series.

Both cards are fabricated on a 5 nm process at TSMC, which places them on the same manufacturing node. The die sizes are close: the Arc B770 measures 368 mm², while the RTX 5080 measures 378 mm². The RTX 5080's transistor count is listed at 45,600 million, giving a density of 120.6M per mm². The Arc B770's transistor count is unknown in the database.

The compute resource allocation differs sharply. The RTX 5080 packs 10,752 shading units, 336 texture mapping units, and 112 ROPs. The Arc B770 has 4,096 shading units, 256 TMUs, and 128 ROPs. Notably, the RTX 5080 has more TMUs despite having fewer ROPs, and its shading unit count is 2.6 times higher.

Ray tracing hardware also diverges: the RTX 5080 has 84 RT cores, while the Arc B770 has 32. The RTX 5080 additionally includes 336 tensor cores, a feature absent from the Arc B770's listed specifications.

The memory architectures are distinct generations. The Arc B770 uses GDDR6 at 2000 MHz (16 Gbps effective), while the RTX 5080 uses GDDR7 at 1875 MHz (30 Gbps effective). Both use a 256-bit bus, but the RTX 5080 reaches 960.0 GB/s versus the Arc B770's 512.0 GB/s.

The FP16 compute paths differ as well. The Arc B770 achieves 39.32 TFLOPS FP16 with a 2:1 ratio to FP32, while the RTX 5080 achieves 56.28 TFLOPS FP16 with a 1:1 ratio. This means the RTX 5080 maintains full-rate FP16 performance, while the Arc B770 halves its FP32 throughput when handling FP16 workloads.

The display outputs are similar in count but differ in versioning: the Arc B770 offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the RTX 5080 offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

Based on the recorded data, the RTX 5080 wins in nearly every measurable category. The Arc B770 shows no benchmark entries in the database, meaning there are no recorded wins for Intel in any test. The head-to-head benchmark list is empty, and the wins counters show 0 for both cards, but the RTX 5080's substantial benchmark presence gives it the clear advantage.

The Arc B770 does have one structural advantage: a lower TDP of 225 W versus 360 W, and a lower suggested PSU of 550 W versus 750 W. For systems with limited power delivery, the Arc B770 is the more accommodating option. Its dual-slot design uses 1x 6-pin plus 1x 8-pin connectors, which are more common in existing power supplies than the RTX 5080's single 16-pin connector.

The RTX 5080 wins on raw compute, memory bandwidth, and feature set. Its 960.0 GB/s bandwidth is nearly double the Arc B770's, and its 56.28 TFLOPS FP32 is roughly three times higher. The tensor cores on the RTX 5080 provide AI acceleration capabilities that the Arc B770 lacks entirely.

The PCIe interface also favors the RTX 5080: PCIe 5.0 x16 versus PCIe 4.0 x16. This doubles the potential data transfer rate between the GPU and the host system, though the practical impact depends on workload.

The release dates differ by about 11 months: the Arc B770 has a release date of 2025-12-31, while the RTX 5080 has a release date of 2025-01-29. The RTX 5080 is marked as Active in production status, while the Arc B770 has no production status listed.

Specification Differences

The two cards differ across nearly all specification fields. The RTX 5080 has a base clock of 2295 MHz and a boost clock of 2617 MHz, both higher than the Arc B770's 2100 MHz base and 2400 MHz boost. The memory clocks differ in type: the Arc B770 runs at 2000 MHz with 16 Gbps effective, while the RTX 5080 runs at 1875 MHz with 30 Gbps effective.

The shading unit count is 10,752 for the RTX 5080 versus 4,096 for the Arc B770. TMUs are 336 versus 256, and ROPs are 112 versus 128. The RTX 5080 has 84 RT cores and 336 tensor cores, while the Arc B770 has 32 RT cores and no tensor cores listed.

Memory type is GDDR7 on the RTX 5080 versus GDDR6 on the Arc B770. Both have 16 GB capacity and 256-bit bus width, but bandwidth is 960.0 GB/s versus 512.0 GB/s.

Pixel rate is 293.1 GPixel/s on the RTX 5080 versus 307.2 GPixel/s on the Arc B770. Texture rate is 879.3 GTexel/s on the RTX 5080 versus 614.4 GTexel/s on the Arc B770. FP32 is 56.28 TFLOPS versus 19.66 TFLOPS, and FP16 is 56.28 TFLOPS versus 39.32 TFLOPS.

Physical dimensions are listed only for the RTX 5080: 304 mm length, 137 mm height, 40 mm width. The Arc B770 has no dimensions recorded.

The RTX 5080 has a launch MSRP of 999 USD. The Arc B770 has no launch MSRP listed.

Head-to-Head Benchmarks

The head-to-head benchmark list between these two cards is empty in the database. The RTX 5080, however, has a full set of recorded benchmark scores that establish its performance profile.

In 3DMark Steel Nomad DX12, the RTX 5080 scores 8,637. In Geekbench OpenCL, it scores 235,901. In Geekbench Vulkan, it scores 255,450. The Passmark suite shows a G3D score of 36,565, a GPU compute score of 21,789, and G2D score of 1,415. Legacy DirectX tests show 389 for DirectX 9, 324 for DirectX 11, 208 for DirectX 10, and 151 for DirectX 12.

The RTX 5080's average benchmark score is 56,083, placing it in the 87th percentile of all GPUs. Its nearest rivals show a tight cluster: the AMD Radeon 8060S scores 55,757 (0.6% behind), the AMD Radeon RX 6750 GRE 12 GB scores 55,698 (0.7% behind), and the AMD Radeon Pro W5700X scores 54,828 (2.3% behind). The AMD Radeon RX 9070 GRE scores 57,367, which is 2.2% ahead of the RTX 5080.

The Arc B770 has no benchmark scores recorded, an average benchmark score of 0, and no nearest rivals listed. Its percentile of 50 places it at the median of all GPUs, but this is based on no actual test data in the database.

The data indicates the RTX 5080 is a high-performance card competing near the top of the recorded benchmark distribution. The Arc B770's absence from benchmark records means no direct comparison of measured performance is possible from the database alone.

The Verdict

The recorded data presents a clear split: the NVIDIA GeForce RTX 5080 is a fully benchmarked, high-performance card with an average score of 56,083 and an 87th percentile ranking. The Intel Arc B770 has no benchmark entries, no average score, and no rival comparisons, leaving its measured performance undocumented in the database.

For users who require validated performance data, the RTX 5080 is the only option with evidence. Its 56.28 TFLOPS FP32, 960.0 GB/s memory bandwidth, and 84 RT cores provide a strong foundation for compute-heavy workloads. The 336 tensor cores add AI acceleration capabilities that the Arc B770 cannot match based on listed specifications.

The Arc B770's advantages are structural rather than performance-based. Its 225 W TDP and 550 W suggested PSU make it easier to integrate into existing systems. The 1x 6-pin plus 1x 8-pin power connectors are more universally compatible than the RTX 5080's 16-pin connector. Its 128 ROPs exceed the RTX 5080's 112, and its pixel rate of 307.2 GPixel/s is slightly higher than the RTX 5080's 293.1 GPixel/s.

The release timeline favors the RTX 5080, which appeared in January 2025 and is marked as Active. The Arc B770's December 2025 release date and lack of production status suggest it is either newer or less established in the market.

The RTX 5080's nearest rivals show it competes within a narrow band: the closest competitor is 0.6% behind, and the strongest is 2.2% ahead. This indicates the RTX 5080 sits in a competitive performance tier. The Arc B770 has no such positioning data.

Given the database contents, the RTX 5080 is the defensible choice for anyone requiring verified benchmark results, higher compute throughput, or AI features. The Arc B770 is suitable for scenarios where lower power draw and standard power connectors take priority, and where the absence of recorded benchmarks is acceptable. The data does not support a performance-based recommendation for the Arc B770.
