Value for money

Performance to price ratio. The higher, the better.

RTX 4090 has 37475% better value for money than GTX 660M Mac Edition.

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	729.6 gflops	no data

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	MXM-B (3.0)	PCIe 4.0 x16
Length	no data	304 mm
Width	MXM Module	3-slot
Supplementary power connectors	None	1x 16-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	GDDR6X
Maximum RAM amount	512 MB	24 GB
Memory bus width	128 Bit	384 Bit
Memory clock speed	5000 MHz	21000 MHz
Memory bandwidth	80 GB/s	1,008 GB/s
Shared memory	no data	-

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	1x HDMI 2.1, 3x DisplayPort 1.4a
HDMI	no data	+
