Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

7900 GS and HD Graphics 405 have a nearly equal value for money.

Detailed specifications

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	450 MHz	320 MHz
Boost clock speed	no data	700 MHz
Number of transistors	278 million	189 million
Manufacturing process technology	90 nm	14 nm
Power consumption (TDP)	49 Watt	6 Watt
Texture fill rate	9.000	11.20
Floating-point performance	no data	213.1 gflops

Form factor & compatibility

Information on GeForce 7900 GS and HD Graphics 405 compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

Interface	PCIe 1.0 x16	PCIe 3.0 x1

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

VRAM capacity and type

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	GDDR3	System Shared
Maximum RAM amount	256 MB	System Shared
Memory bus width	256 Bit	64/128 Bit
Memory clock speed	1320 MHz	System Shared

Connectivity and outputs

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.
