Value for money

Performance to price ratio. The higher, the better.

P104-100 has 349% better value for money than HD 7870 XT.

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.

Floating-point performance	2,995 gflops	8,873 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	267 mm
Width	2-slot	2-slot
Supplementary power connectors	2x 6-pin	1x 8-pin

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	GDDR5X
Maximum RAM amount	2 GB	4 GB
Memory bus width	256 Bit	256 Bit
Memory clock speed	6000 MHz	10008 MHz
Memory bandwidth	192.0 GB/s	320.3 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	1x DVI, 1x HDMI, 2x mini-DisplayPort	No outputs
HDMI	+	no data
