Where Each One Wins

The AMD Radeon RX 6750 GRE 12 GB wins in every measured category where the two cards overlap. In Geekbench Vulkan, it is 144.4% faster. In average benchmark score, it is roughly 33% faster. Its FP32 compute throughput is 13.21 TFLOPS versus 6.832 TFLOPS for the Tesla M40, nearly double. Its texture rate is 413.0 GTexel/s versus 213.5 GTexel/s, and its pixel rate is 165.2 GPixel/s versus 106.8 GPixel/s. Memory bandwidth is also decisively in favor of the RX 6750 GRE: 432.0 GB/s versus 288.4 GB/s. The RX 6750 GRE is the clear choice for any workload that relies on modern graphics APIs, ray tracing, or high-throughput compute.

The NVIDIA Tesla M40 does have one structural advantage: its 384-bit memory bus is wider than the RX 6750 GRE’s 192-bit bus. However, the M40’s slower GDDR5 memory at 6 Gbps effective cannot compensate, and its 288.4 GB/s bandwidth is far below the RX 6750 GRE’s 432.0 GB/s. The M40 also has more shading units (3072 versus 2560) and more texture mapping units (192 versus 160), but its much lower clock speeds, 948 MHz base and 1112 MHz boost versus 2321 MHz base and 2581 MHz boost, negate that raw hardware count. The M40’s higher ROP count (96 versus 64) does not translate into a pixel rate advantage either, as the RX 6750 GRE still wins at 165.2 GPixel/s versus 106.8 GPixel/s.

For use-case selection, the RX 6750 GRE is the only reasonable choice for gaming, real-time ray tracing, or any modern DirectX 12 Ultimate workload. It also has display outputs (1x HDMI 2.1, 3x DisplayPort 1.4a), while the Tesla M40 has no display outputs at all, making it unsuitable as a primary graphics card. The Tesla M40 is an end-of-life compute accelerator with no video outputs, designed for server or compute environments where display output is unnecessary. Its strengths lie in its 12 GB of memory and its status as a legacy Maxwell product, but even in compute tasks, the RX 6750 GRE’s higher FP32 throughput and memory bandwidth make it the faster option in the vast majority of scenarios.

Specification Differences

The AMD Radeon RX 6750 GRE 12 GB is built on the Navi 22 chip using RDNA 2.0 architecture, while the NVIDIA Tesla M40 uses the GM200 chip with Maxwell 2.0 architecture. The process nodes differ significantly: the RX 6750 GRE uses TSMC’s 7 nm process, while the Tesla M40 uses TSMC’s 28 nm process. Transistor counts reflect this: the RX 6750 GRE has 17,200 million transistors on a 335 mm² die, whereas the Tesla M40 has 8,000 million transistors on a larger 601 mm² die. Transistor density is 51.3 million per square millimeter for the RX 6750 GRE versus 13.3 million for the Tesla M40.

The RX 6750 GRE has display outputs, while the Tesla M40 has none. The RX 6750 GRE is 267 mm long, 110 mm high, and 40 mm wide; the Tesla M40 is 267 mm long with no recorded height or width.

Architecture Differences

The architectural gap between these two GPUs is generational. The AMD Radeon RX 6750 GRE 12 GB is part of the Radeon RX 6000 series, based on RDNA 2.0, and belongs to the Navi II (RX 6000) generation. The NVIDIA Tesla M40 belongs to the Tesla Maxwell (Mxx) generation, built on Maxwell 2.0. The RX 6750 GRE is fabricated on a 7 nm process at TSMC, while the Tesla M40 uses a 28 nm process at the same foundry. The smaller process node allows the RX 6750 GRE to pack more than twice the transistors into roughly half the die area, resulting in a transistor density of 51.3 million per square millimeter versus 13.3 million.

The RX 6750 GRE includes 40 dedicated ray tracing cores, a feature entirely absent from the Tesla M40. This allows the RX 6750 GRE to support DirectX 12 Ultimate (12_2), enabling hardware-accelerated ray tracing and variable rate shading. The Tesla M40 is limited to DirectX 12 (12_1), which lacks these modern features. The RX 6750 GRE also supports FP16 compute at 26.43 TFLOPS (2:1 ratio), doubling its FP32 throughput, while the Tesla M40 has no recorded FP16 capability listed in the database, and its FP32 throughput is 6.832 TFLOPS.

Memory architecture differs as well. The RX 6750 GRE uses GDDR6 with 18 Gbps effective speed, delivering 432.0 GB/s bandwidth on a 192-bit interface, while the Tesla M40 uses GDDR5 at 6 Gbps effective, yielding 288.4 GB/s on a 384-bit interface. The Tesla M40, despite its wider bus, cannot overcome the RX 6750 GRE bandwidth deficit.

The RX 6750 GRE also has a game clock of 2439 MHz, a specification that reflects real-world gaming conditions more closely than the Tesla M40 lacks a game clock entirely. The RX 6750 GRE is rated for 12 GB of memory, matching the Tesla M40’s 12 GB. The RX 6750 GRE production status is active, while the Tesla M40 is end-of-life. The RX 6750 GRE was released after the Tesla M40, with the former’s release date recorded as 2023-10-16 and the latter’s as 2015-11-09. The Tesla M40’s predecessor is Tesla Kepler and its successor is Tesla Pascal; the RX 6750 GRE’s predecessor is Navi and its successor is Navi III. The RX 6750 GRE has a launch MSRP of 334 USD.
