Intel Arc B370 vs Intel Arc B770 Comparison

Head-to-Head Benchmarks

The recorded database contains only one direct benchmark score for the Intel Arc B370, leaving the Intel Arc B770 without any comparable measurement in the current dataset. The Arc B370 posts a 3DMark Steel Nomad DX12 score of 1184 points, placing it at the 5th percentile among all GPUs in the database. This indicates that the B370 sits near the lower end of the performance spectrum, well below the median GPU. The Arc B770, by contrast, has no recorded benchmark scores in the database, so head-to-head comparisons cannot be made through direct measurements.

However, the Arc B370's nearest rivals provide useful context for its standing. The ATI Mobility Radeon HD 5570 scores 1186 points, which is 0.2% higher than the B370. The ATI Radeon HD 5770 averages 1190 points, a 0.5% advantage over the B370. The AMD Radeon HD 7650M averages 1192 points, putting it 0.7% ahead. The AMD FirePro M2000 trails with 1168 points, which is 1.4% lower than the B370's score. These deltas are all within roughly one and a half percentage points, indicating that the Arc B370's measured performance clusters very tightly with these older discrete and mobile parts. The data shows that the B370 is essentially at parity with these rivals in the single recorded workload, with no significant win in either direction.

Because the Arc B770 has no benchmark entries and no nearest rivals listed in the database, the head-to-head section for this pair is defined by the absence of comparable data. The B370's 1184 score is the only quantitative anchor available. The B770's 50th percentile ranking among all GPUs, however, suggests that it is positioned at the median of the database's performance distribution. This percentile figure comes from the database's overall ranking, not from a measured score, but it indicates that the B770 belongs to a substantially higher performance tier than the B370, which sits at the 5th percentile. The gap between the 5th and 50th percentiles is large, but without a B770 score, the precise magnitude of that gap cannot be quantified from the recorded data.

Where Each One Wins

The Arc B370's only recorded win is its measured 3DMark Steel Nomad DX12 score of 1184, which beats the AMD FirePro M2000's 1168 average by 1.4%. It also edges out the ATI Mobility Radeon HD 5570 by 0.2%, the ATI Radeon HD 5770 by 0.5%, and the AMD Radeon HD 7650M by 0.7% in reverse order. In other words, the B370 wins against all four nearest rivals in the Steel Nomad test, though the margins are narrow. These wins indicate that the B370 can handle a basic DX12 workload at a level comparable to or slightly better than those older parts, but it does not pull ahead by any substantial margin.

The Arc B770 cannot be assigned wins in any benchmark category because the database contains no scores for it. Its strengths are instead visible in its specifications and its 50th percentile ranking. The B770's integrated memory configuration includes 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s of bandwidth, whereas the B370 relies on system shared memory with bandwidth described as system dependent. This distinction matters for workloads that require large data sets or high memory throughput. The B770 also delivers 19.66 TFLOPS of FP32 compute, 307.2 GPixel/s of pixel throughput, and 614.4 GTexel/s of texture throughput, all of which are far above the B370's 6.144 TFLOPS, 48.00 GPixel/s, and 96.00 GTexel/s.

The B370 wins in power efficiency by design. Its 25 W TDP is dramatically lower than the B770's 225 W TDP, and it requires no power connectors and no additional PSU recommendation. The B370 is an integrated graphics processor, so it occupies no slot and draws power from the host platform. The B770 is a dual-slot discrete card with a 1x 6-pin plus 1x 8-pin power connector arrangement and a suggested PSU of 550 W. For scenarios where power draw and physical footprint are the primary constraints, the B370 is the clear winner based on the recorded data.

Architecture Differences

The two GPUs come from different architectural families and different manufacturing processes. The Intel Arc B370 uses the Panther Lake chip built on Intel's 3 nm process with the Xe3-LPG architecture, and it belongs to the Arc Graphics-M (Panther Lake) generation. The Arc B770 uses the BMG-G31 chip built on TSMC's 5 nm process with the Xe2-HPG architecture, and it belongs to the Battlemage (Arc 7) generation. The B770 lists Alchemist as its predecessor, while the B370 lists no predecessor in the database.

The compute resources differ substantially. The B370 has 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The B770 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. In each category, the B770 has roughly three to over six times the hardware resources of the B370. The B370's FP32 throughput is 6.144 TFLOPS, while the B770's is 19.66 TFLOPS. The FP16 figures follow the same pattern: 12.29 TFLOPS for the B370 and 39.32 TFLOPS for the B770, both listed with a 2:1 ratio relative to FP32.

Memory architecture is another major divergence. The B770 uses 16 GB of GDDR6 memory with a 256-bit bus and 512.0 GB/s of bandwidth. The B370 uses system shared memory with a system shared bus width and system dependent bandwidth. The B770's memory clock is listed as 2000 MHz with 16 Gbps effective data rate, while the B370's memory clock is simply labeled as system shared. The B770's die size is recorded as 368 mm², whereas the B370's die size is unknown in the database. Transistor counts are unknown for both parts.

The B770 operates with a base clock of 2100 MHz and a boost clock of 2400 MHz. The B370 has a base clock of 300 MHz and the same 2400 MHz boost clock. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B770 connects via PCIe 4.0 x16, while the B370 uses an integrated graphics processor bus interface. The B770's display outputs are listed as 1x HDMI 2.1a and 3x DisplayPort 2.1, while the B370's display outputs are portable device dependent. The B770 is a dual-slot card, while the B370 is an IGP with no slot width.

The Verdict

The data presents two very different products. The Intel Arc B370 is an integrated GPU with a 25 W TDP, system shared memory, and a measured 3DMark Steel Nomad DX12 score of 1184, placing it at the 5th percentile. Its nearest rivals are all older ATI and AMD parts with scores within 1.4% of its own, indicating that the B370 occupies the entry-level segment of the performance distribution. It delivers 6.144 TFLOPS of FP32 compute and 48.00 GPixel/s of pixel throughput, which are modest figures. The B370 is suitable for scenarios where the host platform provides the GPU and no discrete card is needed.

The Intel Arc B770 is a discrete, dual-slot card with a 225 W TDP, 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s of bandwidth, and 19.66 TFLOPS of FP32 compute. It sits at the 50th percentile in the database, indicating a median level of performance among all recorded GPUs. The B770 has no measured benchmark scores and no nearest rivals in the database, so its relative standing can only be inferred from its percentile ranking and its specification sheet. It requires a 550 W suggested PSU and uses a 1x 6-pin plus 1x 8-pin power connector arrangement.

The choice between the two depends on the platform and the workload. The B370 is the only option for an integrated solution, and its benchmark score shows it performs at a level comparable to the ATI Mobility Radeon HD 5570 and similar parts. The B770, by contrast, is designed for a discrete slot with dedicated memory and substantially higher throughput in every measured compute category. The B770's 512.0 GB/s of memory bandwidth is a categorical advantage over the B370's system dependent bandwidth. The 50th percentile ranking for the B770 versus the 5th percentile for the B370 indicates that the B770 is positioned far higher in the overall performance distribution, even though no direct benchmark score exists for it. Users with a discrete PCIe 4.0 x16 slot and a sufficient PSU would select the B770 based on its recorded specifications. Users constrained to an integrated GPU would use the B370. The database's current measurements do not provide a common workload score for both parts, so a direct performance comparison cannot be made beyond the percentile and specification evidence.
