NVIDIA GeForce GTX 675MX vs NVIDIA Tesla M10 Comparison

Where Each One Wins

The recorded data splits the two cards cleanly by workload type. The NVIDIA Tesla M10 is the compute-oriented card, built around Maxwell architecture with a focus on server-side acceleration. Its benchmark profile shows a Geekbench OpenCL score of 10,318 and a Geekbench Vulkan score of 9,130, giving it an average benchmark score of 9,724. That places it in the 47th percentile of all GPUs in the database, meaning it sits just above the midpoint of recorded results.

The NVIDIA GeForce GTX 675MX, by contrast, is a mobile GPU from the Kepler generation. Its recorded benchmarks include a Geekbench Metal score of 6,131 and a Geekbench OpenCL score of 10,723, producing an average benchmark score of 8,427. That lands in the 43rd percentile of all GPUs. The interesting wrinkle here is that the GTX 675MX actually wins the only direct head-to-head benchmark in the database, the Geekbench OpenCL test, with a score of 10,723 against the Tesla M10's 10,318. That is a 3.8% margin in favor of the mobile card.

So the use-case split is clear: the Tesla M10 wins on versatility across compute APIs, with both OpenCL and Vulkan results recorded, while the GTX 675MX wins on raw peak OpenCL throughput but has no Vulkan result and instead shows a Metal score. The GTX 675MX also draws far less power, with a 100 W TDP versus the Tesla M10's 225 W, which matters for deployments where thermal and power constraints are tight.

Architecture Differences

The two GPUs come from different architectural generations despite sharing the same 28 nm TSMC process node. The Tesla M10 uses the GM107 chip built on Maxwell, while the GTX 675MX uses the GK104 chip built on Kepler. The transistor counts differ substantially: the Tesla M10 packs 1,870 million transistors on a 148 mm² die, while the GTX 675MX holds 3,540 million transistors on a 294 mm² die. Transistor density is nearly identical, with the M10 at 12.6 million transistors per mm² and the GTX 675MX at 12.0 million per mm².

The compute configurations go in opposite directions from what the die size might suggest. The GTX 675MX has more shading units at 960 versus 640, more texture mapping units at 80 versus 40, and more render output units at 32 versus 16. The Tesla M10 counters with higher clock speeds: a base clock of 1,033 MHz and a boost clock of 1,306 MHz, while the GTX 675MX lists no base or boost clock in the database. The M10's higher clocks push its FP32 throughput to 1.672 TFLOPS, compared to 1,255.7 GFLOPS for the GTX 675MX. Pixel rate also favors the M10 at 20.90 GPixel/s versus 13.08 GPixel/s, while texture rates are essentially tied at 52.24 GTexel/s and 52.32 GTexel/s.

Memory configurations diverge in capacity and bandwidth. The Tesla M10 carries 8 GB of GDDR5 on a 128-bit bus, delivering 83.20 GB/s of bandwidth. The GTX 675MX has 2 GB of GDDR5 on a 256-bit bus, delivering 115.2 GB/s. The mobile card has the narrower capacity but the wider bus and higher bandwidth, which explains its strong OpenCL showing. Effective memory speeds are 5.2 Gbps for the M10 and 3.6 Gbps for the GTX 675MX.

The form factors signal the intended deployment. The Tesla M10 is a dual-slot, 267 mm card with a single 8-pin power connector and a suggested 550 W power supply. It has no display outputs, confirming its role as a compute accelerator. The GTX 675MX is an MXM module with no power connectors and portable-device-dependent display outputs, confirming its laptop orientation. API support is similar for DirectX at 12 (11_0) and OpenGL at 4.6, but the Vulkan versions differ: the M10 supports Vulkan 1.4 while the GTX 675MX supports Vulkan 1.2.175.

The Verdict

The data points to a straightforward conclusion: these are different tools for different jobs, and the right pick depends entirely on the workload and the platform.

For compute workloads in a server or workstation chassis, the Tesla M10 is the stronger choice. It offers 8 GB of memory, which is four times the GTX 675MX's 2 GB, and it shows a higher FP32 throughput at 1.672 TFLOPS. Its Vulkan support is more recent at version 1.4, and its 47th percentile ranking sits above the GTX 675MX's 43rd. The dual-slot form factor and 8-pin connector indicate it is meant to live in a desktop or server enclosure with adequate power delivery.

For mobile deployments or any situation where the GTX 675MX's MXM form factor fits, the mobile card wins the only recorded head-to-head comparison. Its OpenCL score of 10,723 beats the Tesla M10's 10,318 by 3.8%. It also draws 125 W less power, with a 100 W TDP against the M10's 225 W, and it has higher memory bandwidth at 115.2 GB/s. The GTX 675MX is the pick when power efficiency and memory bandwidth matter more than capacity and compute API version support.

The database does not record any Vulkan result for the GTX 675MX, so any comparison on that API is not possible from the available data. Similarly, the Tesla M10 has no Metal result, so the GTX 675MX's Metal score of 6,131 stands alone. Buyers should match the card to the API and form factor their application requires.

Head-to-Head Benchmarks

The only direct head-to-head result in the database is the Geekbench OpenCL test. The GTX 675MX records 10,723 points against the Tesla M10's 10,318, a margin of 3.8% in favor of the mobile Kepler card. This is the single most important comparative data point, and it runs against the expectations set by the average scores.

The average benchmark scores tell a different story. The Tesla M10 averages 9,724 across its two recorded tests, while the GTX 675MX averages 8,427 across its two tests. That is a 15.4% gap in the Tesla M10's favor, entirely attributable to the M10's Vulkan score of 9,130, which has no counterpart in the GTX 675MX's records. The GTX 675MX's Metal score of 6,131 drags its average down, even though its OpenCL result is the best single score between the two cards.

The nearest rival comparisons in the database provide context for each card's standing. The Tesla M10's closest rivals are the NVIDIA Tesla C2070 at 9,716 (0.1% behind), the NVIDIA GeForce GTX 1070 at 9,780 (0.6% ahead), the NVIDIA Quadro P4000 at 9,665 (0.6% behind), and the AMD Radeon Pro WX 2100 at 9,653 (0.7% behind). The GTX 675MX's nearest rivals are the AMD Radeon 880M at 8,436 (0.1% ahead), the NVIDIA GeForce MX330 at 8,458 (0.4% ahead), the AMD Radeon HD 8870M at 8,462 (0.4% ahead), and the AMD Radeon R9 M375X at 8,325 (1.2% behind).

The Tesla M10's percentile placement at 47 means it sits just above the midpoint of all GPUs in the database. The GTX 675MX at the 43rd percentile sits slightly below that midpoint. Yet the direct OpenCL result flips the expected hierarchy, which suggests the GTX 675MX's wider 256-bit memory bus and higher bandwidth compensate for its lower clock speeds and older architecture in this specific workload.

The texture rates are nearly identical, at 52.24 GTexel/s for the Tesla M10 and 52.32 GTexel/s for the GTX 675MX, which means texture-heavy workloads should perform similarly. The FP32 compute rates favor the Tesla M10 at 1.672 TFLOPS versus 1,255.7 GFLOPS, indicating the Maxwell card holds the advantage in pure compute throughput. The pixel rates also favor the M10 at 20.90 GPixel/s versus 13.08 GPixel/s for the GTX 675MX.

The GTX 675MX's OpenCL result being only 3.8% ahead of the Tesla M10, despite having 50% more shading units and 100% more texture units, underscores how much the M10's higher clocks and newer architecture close the gap. The M10 achieves 640 shading units at 1,672 GFLOPS, while the GTX 675MX achieves 960 shading units at 1,255.7 GFLOPS, meaning the Maxwell card extracts more compute per shader.
