Form factor & 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 x1	PCIe 3.0 x16
Width	IGP	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	DDR3L	GDDR6
Maximum RAM amount	8 GB	4 GB
Memory bus width	System Shared	128 Bit
Memory clock speed	System Shared	1250 MHz
Memory bandwidth	no data	160.0 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

4x mini-DisplayPort

API compatibility

List of supported 3D and general-purpose computing APIs, including their specific versions.

DirectX	12 (11_1)	12 (12_1)

Gaming performance

Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.

Average FPS across all PC games

Here are the average frames per second in a large set of popular games across different resolutions:

Full HD	4−5 −2050%	86 +2050%
4K	3−4 −1700%	54 +1700%

Pros & cons summary

Performance score	1.13	19.80
Recency	1 April 2015	6 May 2021
Maximum RAM amount	8 GB	4 GB
Chip lithography	14 nm	12 nm
Power consumption (TDP)	6 Watt	50 Watt

HD Graphics 400 has a 100% higher maximum VRAM amount, and 733.3% lower power consumption.

T1000, on the other hand, has a 1652.2% higher aggregate performance score, an age advantage of 6 years, and a 16.7% more advanced lithography process.

The T1000 is our recommended choice as it beats the HD Graphics 400 in performance tests.
