Intel Arc B770 vs NVIDIA L20 Comparison

Head-to-Head Benchmarks

The database does not contain any direct head-to-head benchmark results between the Intel Arc B770 and the NVIDIA L20. The head-to-head benchmark array is empty, and neither card shows wins in a direct comparison. This absence of recorded side-by-side measurements means the comparison must be constructed from each card's individual recorded performance data, architectural specifications, and the NVIDIA L20's position within the wider GPU landscape.

The NVIDIA L20 has two recorded benchmark scores in the database. Its Geekbench OpenCL score is 274276, and its Geekbench Vulkan score is 228018. These two results combine to produce an average benchmark score of 251147. This average places the L20 at the 99th percentile among all GPUs in the database, which indicates that it sits near the very top of the performance distribution. The Intel Arc B770, by contrast, has no recorded benchmark scores. Its average benchmark score is listed as 0, and its percentile versus all GPUs is 50, which places it exactly at the midpoint of the database distribution. The B770's percentile ranking, however, should be interpreted cautiously because it is derived from a database entry that contains no actual benchmark results.

The L20's nearest rivals in the database provide context for its measured performance. The NVIDIA PG506-232 has an average score of 225124, which is 11.6% lower than the L20's average. The AMD Radeon PRO W7900D has an average score of 219827, which is 14.2% lower. These two deltas show the L20 delivering a clear margin over its closest competitors. On the upper side, the NVIDIA L40 records an average score of 284111, which is 11.6% higher than the L20, and the NVIDIA RTX 6000 Ada Generation records 287237, which is 12.6% higher. The L20 therefore sits in a tight cluster, roughly 12% below the top Ada Lovelace workstation cards and roughly 12% to 14% above the next tier down.

The B770 has no nearest rivals listed in the database, which means there is no measured reference point for its performance relative to any other GPU. Its theoretical compute figures can be compared directly to the L20's, but those are architectural specifications rather than benchmark outcomes. The B770's FP32 throughput is 19.66 TFLOPS, while the L20's is 59.35 TFLOPS, a difference that favors the L20 by a factor of approximately 3. The B770's FP16 throughput is 39.32 TFLOPS (2:1 ratio), while the L20's is 59.35 TFLOPS (1:1 ratio). Here the L20 still leads, but the margin is smaller because the B770's FP16 figure benefits from a doubled rate. The L20's 1:1 FP16 ratio means its FP16 and FP32 rates are identical, which is a notable architectural choice for a server-oriented card.

Where Each One Wins

The NVIDIA L20 wins decisively in raw compute throughput. Its FP32 rate of 59.35 TFLOPS is roughly three times the B770's 19.66 TFLOPS. Its FP16 rate of 59.35 TFLOPS is 1.5 times the B770's 39.32 TFLOPS. The L20 also wins on memory capacity, offering 48 GB versus 16 GB, and on memory bandwidth, offering 864.0 GB/s versus 512.0 GB/s. The L20's 368 tensor cores give it a dedicated hardware path for tensor workloads that the B770 cannot match, as the B770 has no tensor cores recorded. The L20's 92 RT cores versus the B770's 32 suggest a large advantage in ray tracing work. The L20's recorded benchmark scores confirm its high placement: the 99th percentile ranking and an average score of 251147 place it among the top GPUs in the database.

The Intel Arc B770 wins on clock characteristics. Its base clock of 2100 MHz is significantly higher than the L20's 1440 MHz, and its boost clock of 2400 MHz is only 120 MHz below the L20's 2520 MHz. The B770 also draws less power at 225 W versus 275 W, and its suggested PSU is 550 W versus 600 W. The B770 uses a more modern display output set, with HDMI 2.1a and DisplayPort 2.1, while the L20 uses DisplayPort 1.4a only. The B770's smaller die, 368 mm² versus 609 mm², may indicate a more efficient use of silicon area, though the transistor count is unknown. The B770's 2:1 FP16 ratio means its half-precision throughput is double its FP32 rate, which can be advantageous for workloads that use FP16 heavily.

The Verdict

The data supports a clear split. The NVIDIA L20 is the stronger card for compute-heavy, memory-intensive, and server-oriented workloads. Its 59.35 TFLOPS FP32, 48 GB memory, 864.0 GB/s bandwidth, 368 tensor cores, and 92 RT cores place it in a different performance class, and its recorded benchmark results confirm that position with a 99th percentile ranking. The L20's nearest rival data shows it outperforming the NVIDIA PG506-232 by 11.6% and the AMD Radeon PRO W7900D by 14.2%, while trailing the L40 and RTX 6000 Ada Generation by 11.6% and 12.6% respectively. Any workload that scales with FP32 throughput, memory capacity, or tensor core availability will favor the L20.

The Intel Arc B770 is the more modest card in raw numbers but offers a lower power draw, a higher base clock, and more modern display outputs. Its 19.66 TFLOPS FP32 and 16 GB memory are substantially below the L20's figures. The B770 has no recorded benchmark scores, so its real-world performance cannot be verified from the database. Its 50th percentile placement is a default value, not a measured result. The B770's advantages are limited to efficiency-oriented specifications and display connectivity. For users prioritizing raw compute, memory capacity, and tensor performance, the L20 is the clear choice. For users who need a lower-power card with modern display outputs and do not require the L20's massive compute and memory resources, the B770 is the only option that matches those specific characteristics. The two cards occupy different segments, and the recorded data does not give the B770 a single measured performance win over the L20.
