Value for money

Performance to price ratio. The higher, the better.

Tesla K40m has 1371% better value for money than GRID K1.

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.

Core clock speed	850 MHz	745 MHz
Boost clock speed	no data	876 MHz
Number of transistors	1,270 million	7,080 million
Manufacturing process technology	28 nm	28 nm
Power consumption (TDP)	130 Watt	245 Watt

Width	2-slot	2-slot
Supplementary power connectors	1x 6-pin	no data

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	DDR3	GDDR5
Maximum RAM amount	4 GB	12 GB
Memory bus width	128 Bit	384 Bit
Memory clock speed	1782 MHz	6008 MHz
Memory bandwidth	28.51 GB/s	288.4 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

No outputs

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.

GRID K1 1.68

Tesla K40m 8.47
+404%

Tesla K40m outperforms GRID K1 by 404% 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.

Benchmark coverage: 25%
