Let’s analyze the Radeon R7 250 Core Edition (R7-250A-ZLF4) from the traditional manufacturer XFX, a low profile video card with 1 GiB of GDDR5 memory that competes with the GeForce GT 640 GPU from NVIDIA.
The Radeon R7 250 is a rebranded Radeon HD 8670 chip, although according to AMD, the HD 8670 is compatible with DirectX 11.1 and the R7 250 is DirectX 11.2.
It is important to notice that there are video cards based on the Radeon R7 250 GPU using DDR3 memory running at 1.8 GHz (providing a 28.8 GB/s bandwidth).
The Radeon R7 250 uses the PCI Express 3.0 interface, while its main competitor uses the PCI Express 2.0 interface. Although the chip supports PCI Express 3.0 x16, the video card we tested offers only half of the supported lanes and, therefore, it is a PCI Express 3.0 x8 card.
In the table below, we compare the main specifications for the video cards included in our review. The prices were researched at Newegg.com on the day we published this review and do not include rebates.
