Value for money

Performance to price ratio. The higher, the better.

Tesla M6 has 81% better value for money than Tesla K40c.

Technical specs

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Pipelines / CUDA cores	2880	1536
Core clock speed	745 MHz	930 MHz
Boost clock speed	876 MHz	1180 MHz
Number of transistors	7,080 million	5,200 million
Manufacturing process technology	28 nm	28 nm
Power consumption (TDP)	245 Watt	100 Watt
Texture fill rate	210.2	113.3
Floating-point performance	4,291 gflops	3,625 gflops

Size and compatibility

Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).

Interface	PCIe 3.0 x16	PCIe 3.0 x16
Length	267 mm	no data
Width	2-slot	MXM Module
Supplementary power connectors	1x 6-pin + 1x 8-pin	None

Memory

Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.

Memory type	GDDR5	GDDR5
Maximum RAM amount	12 GB	8 GB
Memory bus width	384 Bit	256 Bit
Memory clock speed	6008 MHz	5012 MHz
Memory bandwidth	288.4 GB/s	160.4 GB/s

Video outputs and ports

Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.

Display Connectors

Combined synthetic benchmark score

This is our combined benchmark performance score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.

Tesla K40c 11.60

Tesla M6 15.32
+32.1%

Tesla M6 outperforms Tesla K40c by 32% based on our aggregated benchmark results.

Passmark

This is the most ubiquitous GPU benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
