Architecture Differences

The Tesla M40 24 GB is built on the GM200 chip using Maxwell 2.0 architecture, manufactured on a 28 nm process at TSMC. The die measures 601 mm² and contains 8,000 million transistors. This is a large, power-hungry server-oriented design. The T600 Mobile, in contrast, uses the TU117 chip with Turing architecture, fabricated on a 12 nm process at TSMC. Its die is much smaller at 200 mm², containing 4,700 million transistors. The T600 Mobile's transistor density is significantly higher at 23.5 million per mm² compared to the Tesla M40 24 GB's 13.3 million per mm², reflecting the newer manufacturing technology.

The compute resources differ dramatically. The Tesla M40 24 GB packs 3,072 shading units, 192 texture mapping units, and 96 raster operation pipelines. The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. In terms of raw throughput, the Tesla M40 24 GB delivers 6.832 TFLOPS of FP32 compute, while the T600 Mobile achieves 2.527 TFLOPS. Notably, the T600 Mobile supports FP16 at 5.053 TFLOPS with a 2:1 ratio, while the Tesla M40 24 GB does not have a recorded FP16 figure.

Memory architecture is another major differentiator. The Tesla M40 24 GB uses 24 GB of GDDR5 with a 384-bit bus and 288.4 GB/s bandwidth. The T600 Mobile uses 4 GB of GDDR6 on a 128-bit bus with 192.0 GB/s bandwidth. The Tesla M40 24 GB also operates at a higher base clock of 948 MHz with a boost of 1112 MHz, whereas the T600 Mobile has a lower base clock of 780 MHz but a higher boost clock of 1410 MHz. The Tesla M40 24 GB draws 250 W and requires a dual-slot cooler with an 8-pin EPS power connector, plus a 600 W suggested power supply. The T600 Mobile is an integrated graphics processor with a 40 W TDP, no power connectors, and no dedicated power supply recommendation.

Head-to-Head Benchmarks

The recorded head-to-head results show the Tesla M40 24 GB winning both tests. In Geekbench OpenCL, the Tesla M40 24 GB scores 37,439 against the T600 Mobile's 35,486, a 5.5 percent advantage. This is a relatively close result, suggesting that OpenCL workloads do not fully expose the hardware differences between the two cards. The T600 Mobile's Turing architecture, with its higher boost clock and FP16 support, may help it close the gap in certain compute patterns.

The Geekbench Vulkan test tells a very different story. The Tesla M40 24 GB scores 45,975, while the T600 Mobile scores 30,211. The 52.2 percent margin in favor of the Tesla M40 24 GB is the largest performance difference recorded between the two. This result likely reflects the Tesla M40 24 GB's massive memory bandwidth advantage (288.4 GB/s versus 192.0 GB/s), its much higher texture fill rate (213.5 GTexel/s versus 78.96 GTexel/s), and its larger pool of shading units. The pixel rate also favors the Tesla M40 24 GB at 106.8 GPixel/s versus 45.12 GPixel/s.

Looking at the broader context, the Tesla M40 24 GB's average score of 41,707 puts it 0.5 percent behind the NVIDIA Tesla M40 (which scores 41,897) and 1.3 percent ahead of the NVIDIA GeForce RTX 3080 Ti (41,187). It also sits 2 percent above the AMD Radeon Pro 5300 (40,870) and 2.4 percent below the AMD Radeon RX 7650 GRE (42,723). The T600 Mobile's average of 32,849 places it 0.4 percent behind the NVIDIA P104-100 (32,982), 0.8 percent above the AMD Radeon RX 590 GME (32,601), 0.9 percent above the AMD FirePro S9300 X2 (32,540), and 0.9 percent below the NVIDIA T550 Mobile (33,161). These nearest-rival comparisons show that the Tesla M40 24 GB competes at a higher performance tier overall.

The Verdict

The data is unambiguous: the NVIDIA Tesla M40 24 GB is the faster GPU by a wide margin. It wins both benchmark tests, holds a higher average score, and ranks higher in the database percentile distribution. For any workload that can use the Tesla M40 24 GB, it is the stronger performer. However, the Tesla M40 24 GB is a server accelerator with no display outputs, a 250 W power draw, and a dual-slot form factor. It is not suitable for mobile workstations or any system requiring video output. The T600 Mobile, with its 40 W TDP, integrated form factor, and portable device dependent display outputs, is designed for laptops where power efficiency and small footprint are essential. The choice between these two comes down to the intended use case: the Tesla M40 24 GB for high-throughput compute in a server environment, or the T600 Mobile for mobile workstation tasks where the lower power draw and display connectivity matter more than raw performance.

Where Each One Wins

The Tesla M40 24 GB wins in every recorded benchmark category. Its strengths lie in raw compute throughput, memory bandwidth, and fill rates. The 6.832 TFLOPS FP32 performance, 288.4 GB/s memory bandwidth, and 213.5 GTexel/s texture rate make it suitable for compute-heavy tasks such as large-scale data processing, scientific simulations, and deep learning inference where memory capacity is critical. The 24 GB VRAM is particularly valuable for workloads that require loading large datasets into GPU memory. The Tesla M40 24 GB also wins decisively in Vulkan, with a 52.2 percent lead, suggesting that applications leveraging the Vulkan API will see substantial performance benefits.

The T600 Mobile wins in areas that are not captured by raw benchmark scores. Its 40 W TDP is a fraction of the Tesla M40 24 GB's 250 W, making it suitable for battery-powered laptops and compact mobile workstations. The Turing architecture provides FP16 support at 5.053 TFLOPS, which the Tesla M40 24 GB does not offer, potentially benefiting workloads that can use mixed-precision computation. The T600 Mobile also has display outputs (portable device dependent), while the Tesla M40 24 GB has none, meaning the T600 Mobile can drive a laptop panel. The T600 Mobile's smaller die size and higher transistor density reflect a more modern design, and its higher boost clock of 1410 MHz suggests better clock scaling in thermally constrained environments. For mobile professionals who need GPU acceleration in a laptop, the T600 Mobile is the only viable choice between these two. For server rooms or desktop workstations where power draw and physical size are not concerns, the Tesla M40 24 GB offers far superior performance.
