Intel Arc B570 vs NVIDIA Tesla K40c Comparison

Where Each One Wins

The recorded benchmark data presents a clear, though limited, comparison between these two GPUs. The Intel Arc B570 and NVIDIA Tesla K40c share only one common benchmark in the database: Geekbench OpenCL. In that single head-to-head test, the Intel Arc B570 wins decisively. The Arc B570 records a score of 83,514, while the Tesla K40c manages 17,468. This represents a 378.1% advantage for the Intel card, a substantial margin that defines the entire competitive landscape between these products.

The Intel Arc B570 also has a much broader benchmark footprint in the database. Beyond the shared OpenCL test, it has recorded scores in 3DMark Steel Nomad DX12, Geekbench Vulkan, and multiple Passmark tests including DirectX 9, 10, 11, 12, G2D, G3D, and GPU Compute. The Tesla K40c, by contrast, has only the single OpenCL entry. This means the Arc B570's database profile demonstrates versatility across gaming and compute workloads, while the Tesla K40c's recorded data is limited to compute-oriented OpenCL performance.

In terms of overall standing, the Arc B570 sits at the 65th percentile among all GPUs in the database, with an average benchmark score of 20,556. The Tesla K40c sits at the 61st percentile, with an average score of 17,468. The percentile difference is modest, but the average score gap is significant. The Arc B570's nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (0.1% ahead), the Intel Arc A750 (0.1% behind), the NVIDIA Quadro M4000M (0.4% ahead), and the AMD Radeon R9 M390X (0.5% behind). The Tesla K40c's nearest rivals are the AMD Radeon Pro 460 (0.2% ahead), AMD Radeon Pro 560 (0.5% ahead), AMD Radeon 780M (0.7% ahead), and NVIDIA GeForce RTX 4060 (1% ahead).

Architecture Differences

The architectural gap between these two GPUs is generational. The Intel Arc B570 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage generation (Arc 5). It is fabricated on a 5 nm process at TSMC, with 19,600 million transistors on a 272 mm² die. This yields a transistor density of 72.1 million transistors per square millimeter. The NVIDIA Tesla K40c uses the GK180 chip based on the Kepler architecture, belonging to the Tesla Kepler (Kxx) generation. It is built on a 28 nm process, also at TSMC, with 7,080 million transistors on a much larger 561 mm² die. Its transistor density is only 12.6 million transistors per square millimeter.

The memory subsystems differ substantially. The Arc B570 has 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The Tesla K40c has 12 GB of GDDR5 memory on a 384-bit bus, delivering 288.4 GB/s. Although the Tesla has more memory and a wider bus, its older memory technology and lower clock speeds result in lower bandwidth. The Arc B570's memory runs at 2375 MHz (19 Gbps effective), while the Tesla's memory runs at 1502 MHz (6 Gbps effective).

Compute resources also differ in configuration. The Arc B570 has 2,304 shading units, 144 texture mapping units, 80 raster output units, and 18 ray tracing cores. The Tesla K40c has 2,880 shading units, 240 TMUs, and 48 ROPs, but no ray tracing cores. The Tesla has more raw shading units and TMUs, but the Arc B570 compensates with much higher clock speeds: 2500 MHz base and boost for the Intel card versus 745 MHz base and 876 MHz boost for the NVIDIA card. The Arc B570 also supports FP16 compute at 23.04 TFLOPS (2:1 ratio), while the Tesla K40c has no recorded FP16 capability.

Head-to-Head Benchmarks

The only direct comparison available in the database is the Geekbench OpenCL test. The Intel Arc B570 scores 83,514, while the NVIDIA Tesla K40c scores 17,468. The Intel card leads by 378.1%, which is a massive difference. To put this in context, the Arc B570's OpenCL score alone is nearly five times that of the Tesla K40c's entire average benchmark score.

This result aligns with the broader performance profiles of each card. The Arc B570's average benchmark score across all its tests is 20,556, which is 17.7% higher than the Tesla K40c's 17,468. However, the OpenCL gap is far larger than the average gap would suggest. This indicates that the Arc B570's advantage is particularly pronounced in compute workloads, where its modern architecture, higher clocks, and faster memory produce outsized gains.

The Arc B570's other recorded benchmarks show a well-rounded profile. Its Passmark G3D score is 14,195, its Passmark GPU Compute score is 7,281, its 3DMark Steel Nomad DX12 score is 2,649, and its Geekbench Vulkan score is 96,844. The Tesla K40c has no comparable entries in these tests, so the database cannot provide a direct comparison for gaming or DirectX workloads. The available data, however, suggests the Arc B570 is the stronger performer across the board.

The Verdict

The data points to a clear conclusion: the Intel Arc B570 is the superior performer in every measurable category. Its OpenCL score is 378.1% higher than the Tesla K40c's, its average benchmark score is 17.7% higher, and its percentile ranking is higher as well. The architectural advantages are decisive. The Arc B570 uses a modern 5 nm process with 72.1 million transistors per mm², compared to the Tesla's 28 nm process with 12.6 million per mm². The Arc B570's clock speeds are over three times higher, and its memory bandwidth is 31.8% higher despite a narrower bus.

For compute workloads, the Arc B570 is the obvious choice. Its FP32 performance of 11.52 TFLOPS more than doubles the Tesla K40c's 5.046 TFLOPS. The Arc B570 also adds FP16 support at 23.04 TFLOPS, ray tracing cores, and modern API support including DirectX 12 Ultimate and Vulkan 1.4. The Tesla K40c lacks ray tracing, lacks FP16, and supports only DirectX 12 (11_0) and Vulkan 1.2.175.

The Tesla K40c does have advantages in raw configuration: more shading units (2,880 vs 2,304), more TMUs (240 vs 144), more memory (12 GB vs 10 GB), and a wider memory bus (384-bit vs 160-bit). It also supports PCIe 3.0 x16, which is a wider interface than the Arc B570's PCIe 4.0 x8. However, these advantages do not translate into benchmark wins. The Tesla's lower clocks and older architecture negate its wider resources.

For gaming or general-purpose graphics work, the Arc B570 is also the better pick. It has display outputs (1x HDMI 2.1a and 3x DisplayPort 2.1), while the Tesla K40c has no display outputs at all. The Arc B570 supports modern DirectX 12 Ultimate features and has a full suite of Passmark scores showing strong DirectX 9, 10, 11, and 12 performance. The Tesla K40c has none of these recorded results.

The production status seals the decision. The Arc B570 is active and current, released in January 2025. The Tesla K40c is end-of-life, released in October 2013, with its successor (Tesla Maxwell) already recorded. For any new deployment, the Intel Arc B570 is the rational choice based on the recorded data. The Tesla K40c remains a historical artifact with a single benchmark entry and no competitive standing against its modern counterpart.
