Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

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.

Pipelines / CUDA cores	800	480
Core clock speed	500 MHz	800 MHz
Number of transistors	956 million	716 million
Manufacturing process technology	55 nm	40 nm
Power consumption (TDP)	no data	66 Watt
Texture fill rate	20.00	19.20
Floating-point performance	800.0 gflops	768.0 gflops

Form factor & compatibility

Information on Mobility Radeon HD 4850 and Radeon HD 7670 OEM 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.

Laptop size	large	no data
Interface	PCIe 2.0 x16	PCIe 2.0 x16
Length	no data	145 mm
Width	no data	1-slot
Supplementary power connectors	no data	None

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	GDDR5
Maximum RAM amount	1 GB	512 MB
Memory bus width	256 Bit	128 Bit
Memory clock speed	850 MHz	4000 MHz
Memory bandwidth	54.4 GB/s	64 GB/s

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.

Display Connectors

No outputs

1x DVI, 1x DisplayPort, 1x VGA
