XFX Radeon R7 240 / 250 Passive review: no fan, low price

The cheapest Radeon R7 cards have no fans

Introduction

In early October AMD launched the first Radeon R9 and R7 video cards. We tested the Radeon R9 280X, R9 270X and R7 260X already, and today we're going to look at two lower-positioned cards: the Radeon R7 250 and 240.


Oland GPU

The Radeon R7 250 and 240 are the entry-level cards in AMD's new family. Both are based on the Oland GPU that until now had only been used for laptop and OEM cards. The Radeon HD 8570 and 8670 cards and the mobile Radeon HM 8500M, 8600M and 8700M series use the Oland GPU. 

Oland is a Graphics Core Next chip with 384 shader units and 24 texture units. That makes it smaller than the Cape Verde chip in the Radeon HD 7750 and 7770, with 640 shader units. Oland uses a 128-bit memory controller that works with both GDDR5 and the slower DDR3 RAM.

On Radeon R7 250 cards all 384 shader units of the Oland GPU are enabled and the GPU is clocked at 1050 MHz. Most R7 250 cards have GDDR5 video memory with a clockspeed of 1150 MHz, either 1GB or 2GB. The TDP of the R7 250 is 65W, and in terms of pricing it's positioned against the Nvidia GeForce GT 640.

Radeon R7 240 cards have only 320 active shader units and the GPU is a little slower with 780 MHz. The R7 240 supports both GDDR5 and DDR3 memory, but DDR3 is more common here. It's clocked at 900 MHz. The R7 240 is a very efficient card with a TDP of only 30W. The R7 240 is positioned against the Nvidia GeForce GT 630. 

Here are the specs of the R7 250 and R240:
