NVIDIA GeForce RTX 3070 Ti Mobile vs NVIDIA Tesla K40m Comparison

The Verdict

The benchmark database places the NVIDIA GeForce RTX 3070 Ti Mobile and the NVIDIA Tesla K40m in different performance tiers, despite both being end-of-life products. The RTX 3070 Ti Mobile is the decisive winner in the only shared benchmark, scoring 106,022 points in Geekbench OpenCL against the Tesla K40m's 19,885 points, a 433.2% advantage. The RTX 3070 Ti Mobile also holds a higher overall percentile ranking at 69 versus the Tesla K40m's 65, meaning it outperforms a larger share of all GPUs in the database. For any workload relying on OpenCL compute, the RTX 3070 Ti Mobile is the clear choice based on recorded data. The Tesla K40m, with its older Kepler architecture and lower FP32 throughput, is only relevant for legacy compute tasks or systems that specifically require its 12 GB memory capacity and dual-slot form factor.

Architecture Differences

The two GPUs come from entirely different NVIDIA architectures, separated by roughly eight years of development. The RTX 3070 Ti Mobile uses the GA104 chip built on the Ampere architecture, manufactured by Samsung on an 8 nm process. The Tesla K40m uses the GK110B chip built on the older Kepler architecture, manufactured by TSMC on a 28 nm process. This process difference is stark: the Ampere chip packs 17,400 million transistors into a 392 mm² die, achieving a transistor density of 44.4 million transistors per square millimeter. The Kepler chip contains 7,080 million transistors spread across a larger 561 mm² die, yielding only 12.6 million transistors per square millimeter.

The architectural gap shows in feature support. The RTX 3070 Ti Mobile includes 46 ray tracing cores and 184 tensor cores, neither of which exist on the Tesla K40m (both fields are null in the database). The Ampere GPU also supports FP16 compute at a 1:1 ratio with FP32, delivering 16.60 TFLOPS for both precision types. The Kepler GPU has no recorded FP16 capability at all. The shading unit counts reflect the different design philosophies: the RTX 3070 Ti Mobile has 5,888 shading units, 184 texture mapping units, and 96 raster operation units, while the Tesla K40m has 2,880 shading units, 240 TMUs, and 48 ROPs. The Tesla K40m's higher TMU count relative to its shading units suggests a design aimed at texture-heavy workloads, but its lower overall core count limits its modern compute performance.

The RTX 3070 Ti Mobile belongs to the GeForce 30-series, with its predecessor being the GeForce 20 Mobile series. The Tesla K40m belongs to the Tesla Kepler generation (Kxx), with its predecessor being Tesla Fermi and its successor being Tesla Maxwell. The Tesla K40m is a compute-focused accelerator with no display outputs, while the RTX 3070 Ti Mobile has portable device dependent display outputs, reflecting its mobile gaming and workstation positioning.

Specification Differences

The database records several key specification differences between the two GPUs. The RTX 3070 Ti Mobile has a base clock of 915 MHz and a boost clock of 1410 MHz, while the Tesla K40m runs at a base clock of 745 MHz and a boost clock of 876 MHz. The Ampere GPU's memory runs at 1750 MHz with 14 Gbps effective speed, while the Kepler GPU's memory runs at 1502 MHz with 6 Gbps effective speed. Memory bandwidth favors the RTX 3070 Ti Mobile at 448.0 GB/s versus 288.4 GB/s for the Tesla K40m, despite the Tesla card having a wider 384-bit bus versus 256-bit. The Tesla K40m compensates with 12 GB of GDDR5 memory versus 8 GB of GDDR6 on the RTX 3070 Ti Mobile.

Pixel and texture rates show the Ampere GPU's advantage. The RTX 3070 Ti Mobile achieves 135.4 GPixel/s and 259.4 GTexel/s, while the Tesla K40m achieves 52.56 GPixel/s and 210.2 GTexel/s. FP32 compute is dramatically different: 16.60 TFLOPS for the RTX 3070 Ti Mobile versus 5.046 TFLOPS for the Tesla K40m. Power consumption reverses the performance trend, with the RTX 3070 Ti Mobile drawing 115 W TDP versus 245 W for the Tesla K40m. The Tesla K40m is a dual-slot card measuring 267 mm (10.5 inches) in length, requires a 550 W suggested PSU, and has no power connector details recorded. The RTX 3070 Ti Mobile has no recorded dimensions, no power connectors, and no suggested PSU. Bus interface differs as well: the RTX 3070 Ti Mobile uses PCIe 4.0 x16, while the Tesla K40m uses PCIe 3.0 x16. The Tesla K40m has no display outputs, while the RTX 3070 Ti Mobile's outputs are described as portable device dependent.

Head-to-Head Benchmarks

The database contains exactly one head-to-head benchmark between these two GPUs: Geekbench OpenCL. The results are lopsided. The RTX 3070 Ti Mobile scores 106,022 points, while the Tesla K40m scores 19,885 points. The delta is 433.2% in favor of the RTX 3070 Ti Mobile. This single result drives the win count to 1 for the RTX 3070 Ti Mobile and 0 for the Tesla K40m.

This OpenCL result is consistent with the broader benchmark data in the database. The RTX 3070 Ti Mobile's average benchmark score of 23,518 places it among a group of nearby rivals including the NVIDIA GeForce RTX 3080 Mobile (23,628, 0.5% behind), the AMD Radeon AI PRO R9700 (23,315, 0.9% ahead), the NVIDIA GeForce GTX TITAN Z (23,736, 0.9% behind), and the AMD Radeon R9 M290X (23,276, 1% ahead). The RTX 3070 Ti Mobile sits essentially in the middle of this pack, with its closest rival being the RTX 3080 Mobile at a 0.5% deficit. The Tesla K40m's average benchmark score of 19,885 places it near the AMD FirePro W7000 (19,905, 0.1% behind), the AMD Radeon RX 6650 XT (19,765, 0.6% ahead), the AMD FirePro D300 (19,637, 1.3% ahead), and the NVIDIA Quadro K5200 (19,602, 1.4% ahead). The Tesla K40m is essentially tied with the FirePro W7000 in this grouping.

The RTX 3070 Ti Mobile's other benchmark results, while not directly comparable to the Tesla K40m in the head-to-head table, show its range of capabilities. It scores 2,572 in 3DMark Steel Nomad DX12, 100,027 in Geekbench Vulkan, 17,727 in Passmark G3D, and 7,504 in Passmark GPU Compute. Its Passmark DirectX scores are 124 for DX10, 153 for DX11, 73 for DX12, and 196 for DX9, with a 2D score of 783. These numbers indicate a GPU that performs best in modern API workloads, particularly Vulkan and OpenCL, and less impressively in legacy DirectX tests. The Tesla K40m has only the single OpenCL result in the database, which limits direct comparisons but underscores that its compute-oriented design is its only recorded strength. The RTX 3070 Ti Mobile's 433.2% lead in OpenCL is the defining metric in this pairing.
