The Arc B770 has no recorded benchmark scores or rivals in the database.

Architecture Differences

The Intel Arc B770 and NVIDIA RTX 5880 Ada Generation represent two fundamentally different design philosophies within the same process generation. Both use TSMC's 5 nm process, but the similarities end there. The B770's BMG-G31 chip is built on Intel's Xe2-HPG architecture, part of the Battlemage generation within the Arc 7 lineup. The RTX 5880 uses the AD102 chip with NVIDIA's Ada Lovelace architecture, belonging to the Workstation Ada generation.

The transistor counts reveal a massive scale difference. The RTX 5880 packs 76,300 million transistors into a 609 mm² die, achieving a transistor density of 125.3 million per square millimeter. The Arc B770's transistor count is not recorded, but its die size of 368 mm² is significantly smaller. This scale difference translates directly into compute resources: the RTX 5880 has 14,080 shading units versus 4,096 on the B770, 440 TMUs versus 256, 176 ROPs versus 128, and 110 RT cores versus 32.

The RTX 5880 also includes 440 tensor cores, a feature the Arc B770 does not list. Clock behavior differs notably as well. The Arc B770 has a base clock of 2100 MHz and a boost of 2400 MHz, while the RTX 5880 starts much lower at 975 MHz but boosts to 2460 MHz. This suggests the NVIDIA card relies on its massive parallel resources rather than high base clocks, while Intel pushes higher idle speeds.

Memory architecture is another major divider. The B770 uses 16 GB of GDDR6 on a 256-bit bus at 2000 MHz (16 Gbps effective), producing 512.0 GB/s. The RTX 5880 uses 48 GB of GDDR6 on a 384-bit bus at 2250 MHz (18 Gbps effective), producing 864.0 GB/s. The NVIDIA card's memory controller is wider and faster, which matters for data-heavy workloads.

Display outputs differ as well. The Arc B770 provides one HDMI 2.1a port and three DisplayPort 2.1 outputs, while the RTX 5880 offers four DisplayPort 1.4a outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5880 has a recorded physical size of 267 mm in length and 112 mm in height, while the B770's dimensions are not listed.

Where Each One Wins

Based on the recorded data, the Intel Arc B770 has no benchmark scores in the database, so its wins cannot be quantified. The NVIDIA RTX 5880 Ada Generation, however, has a clear profile across multiple tests. Its strongest results come from general compute and 3D rendering workloads.

The RTX 5880's Geekbench OpenCL score of 326,898 indicates strong general-purpose compute capability. Its Passmark G3D score of 25,096 shows solid 3D rendering performance. The Passmark GPU Compute score of 14,208 confirms that the card handles compute-heavy tasks well. The card's 85th percentile ranking among all GPUs places it well above the median, and its average benchmark score of 45,972 positions it competitively against its nearest rivals.

The Arc B770's architecture suggests it could be competitive in specific scenarios, but without recorded benchmarks, those wins remain unverified. The B770's higher base clock of 2100 MHz versus 975 MHz could benefit latency-sensitive workloads, but no data confirms this. The B770's smaller memory footprint of 16 GB versus 48 GB limits its applicability in memory-intensive tasks like large model inference or high-resolution texture workloads.

The RTX 5880's nearest rival data provides context for its positioning. It sits within a tight cluster: the RTX A2000 scores 46,043 (-0.2%), the Arc A730M scores 45,592 (+0.8%), the Radeon Pro 5500 XT scores 45,384 (+1.3%), and the Radeon RX 5600M scores 46,601 (-1.4%). This places the RTX 5880 in a competitive mid-pack, not dominating but not trailing significantly either.

Specification Differences

The two cards differ in nearly every measurable specification. The Arc B770 uses the BMG-G31 chip with Xe2-HPG architecture from the Battlemage generation, while the RTX 5880 uses the AD102 chip with Ada Lovelace architecture from the Workstation Ada generation. Intel's card has no listed successor or predecessor beyond "Alchemist" as its predecessor, while NVIDIA's card lists "Workstation Ampere" as its predecessor and "Blackwell PRO W" as its successor.

Process node and foundry are identical: both use TSMC's 5 nm process. Die size differs substantially at 368 mm² for the B770 versus 609 mm² for the RTX 5880. Transistor count is unknown for the B770 but recorded at 76,300 million for the RTX 5880, giving the latter a density of 125.3 million transistors per square millimeter.

Clock speeds differ in both base and boost: the B770 runs at 2100 MHz base and 2400 MHz boost, while the RTX 5880 runs at 975 MHz base and 2460 MHz boost. Memory clocks also differ: 2000 MHz (16 Gbps effective) for the B770 versus 2250 MHz (18 Gbps effective) for the RTX 5880.

Memory capacity, bus width, and bandwidth all favor the NVIDIA card: 48 GB versus 16 GB, 384-bit versus 256-bit, and 864.0 GB/s versus 512.0 GB/s. The compute resources show a similar pattern: 14,080 shading units versus 4,096, 440 TMUs versus 256, 176 ROPs versus 128, 110 RT cores versus 32, and 440 tensor cores versus none listed.

Pixel rate and texture rate both favor the RTX 5880: 433.0 GPixel/s versus 307.2 GPixel/s, and 1,082.4 GTexel/s versus 614.4 GTexel/s. FP32 compute is 69.27 TFLOPS versus 19.66 TFLOPS, and FP16 is 69.27 TFLOPS (1:1) versus 39.32 TFLOPS (2:1).

Power specifications differ as well: the B770 has a 225 W TDP with a 550 W suggested PSU and 1x 6-pin plus 1x 8-pin connectors, while the RTX 5880 has a 285 W TDP with a 600 W suggested PSU and a single 16-pin connector. Both are dual-slot cards. The RTX 5880 is listed as Active in production status and has recorded dimensions of 267 mm length and 112 mm height, while the B770's status and dimensions are not recorded.

Head-to-Head Benchmarks

The head-to-head benchmark comparison between these two cards is limited by available data. The database records no head-to-head benchmark results, and the Intel Arc B770 has no individual benchmark scores. The NVIDIA RTX 5880 Ada Generation, however, has eight recorded benchmark scores that provide a baseline for analysis.

The RTX 5880's strongest recorded result is in Geekbench OpenCL with a score of 326,898. This indicates substantial compute throughput in OpenCL workloads, which aligns with its 69.27 TFLOPS FP32 rating. The Passmark G3D score of 25,096 shows respectable 3D rendering performance, while the Passmark GPU Compute score of 14,208 confirms compute capability outside pure graphics.

In legacy DirectX tests, the RTX 5880 shows interesting variation. Its Passmark DirectX 9 score of 335 and DirectX 10 score of 167 indicate moderate performance in older APIs. The DirectX 11 score of 228 and DirectX 12 score of 70 are notably lower, suggesting the card's architecture prioritizes newer compute paradigms over legacy rasterization paths. The Passmark G2D score of 777 covers 2D graphics operations.

The Arc B770's absence from the benchmark database means no direct comparison is possible. The B770's theoretical specifications, such as 19.66 TFLOPS FP32 and 512.0 GB/s bandwidth, are far below the RTX 5880's 69.27 TFLOPS and 864.0 GB/s. The pixel rate difference (307.2 GPixel/s versus 433.0 GPixel/s) and texture rate difference (614.4 GTexel/s versus 1,082.4 GTexel/s) further indicate the NVIDIA card holds a clear advantage in raw throughput.

The RTX 5880's nearest rival comparisons provide additional context. Its average benchmark score of 45,972 places it within 1.4% of the AMD Radeon RX 5600M (46,601), within 0.2% of the NVIDIA RTX A2000 (46,043), and ahead of the Intel Arc A730M (45,592, +0.8%) and AMD Radeon Pro 5500 XT (45,384, +1.3%). This tight clustering suggests the RTX 5880 competes in a crowded performance tier rather than dominating it.

The Verdict

The recorded data presents an asymmetric comparison. The NVIDIA RTX 5880 Ada Generation has a complete benchmark profile, an 85th percentile ranking, and an average score of 45,972. The Intel Arc B770 has no recorded benchmarks, no nearest rivals, and a 50th percentile ranking that reflects the absence of test results rather than measured performance.

For users selecting between these two cards, the data clearly favors the RTX 5880 in every measured category. Its 48 GB memory capacity, 864.0 GB/s bandwidth, 69.27 TFLOPS FP32, and 110 RT cores provide a substantial foundation for compute-heavy and graphics-intensive workloads. The recorded benchmark scores confirm that this theoretical advantage translates into practical performance in OpenCL, 3D rendering, and general compute tasks.

The Arc B770's specifications suggest it could serve lighter workloads. Its 16 GB memory and 512.0 GB/s bandwidth are adequate for less demanding applications, and its 225 W TDP is lower than the RTX 5880's 285 W. The B770's higher base clock of 2100 MHz could benefit workloads that respond to clock speed rather than raw parallel throughput. However, without benchmark data, these possibilities remain speculative.

The RTX 5880's nearest rival data shows it sits in a competitive performance band. It essentially matches the RTX A2000 (-0.2%) and RX 5600M (-1.4%), while leading the Arc A730M (+0.8%) and Radeon Pro 5500 XT (+1.3%). This indicates the RTX 5880's performance is solid but not exceptional within its peer group.

The production status also differs: the RTX 5880 is listed as Active, while the B770 has no recorded status. The RTX 5880's release date of January 2024 and its listed successor (Blackwell PRO W) indicate a mature product with a clear lifecycle. The B770's release date of December 2025 and its predecessor (Alchemist) suggest a newer entry in Intel's Arc lineup.

Users requiring large memory capacity, high compute throughput, and validated performance across multiple benchmark suites should prioritize the RTX 5880 Ada Generation. Users seeking a lower-power alternative with newer display outputs (DisplayPort 2.1 versus 1.4a) might consider the Arc B770, but they would do so without the benchmark validation that the RTX 5880 enjoys. The data supports the RTX 5880 as the more capable and better-characterized option.
