At yesterday's press event, AMD announced three new mobile Radeons: the R5 M230, R7 M265, and R9 M290X. The company didn't disclose specifications at the time, but it's now rectified that omission—or at least, partially so. Full product pages for the R9 M290X and the R5 M230 have popped up on the company's website, and here's what they tell us:
|Radeon R9 M290X
||850||up to 900||1280||80||32||4.8 GT/s||256|
|Radeon R5 M230
||?||up to 855||320||20||4||2.0 GT/s||64|
AMD says both models can be paired with up to 4GB of RAM, as well.
4GB may be overkill for the R5 M230, which looks pretty pared-down even for a mobile GPU. Its specs resemble those of the Radeon HD 8570M, which debuted a little over a year ago. From what I've been able to gather (mostly by digging around on Wikipedia), the Radeon HD 8570M is based on the 28-nm Sun GPU, which appears to be the mobile counterpart of Oland. I suspect the R5 M230 is built with the same silicon as the 8570M.
As for the R9 M290X, that puppy's specifications match those of the Radeon HD 8970M pretty much to a tee. The core and memory clock speeds are identical, as are the unit counts and memory interface widths. The Radeon HD 8970M came out last May; it was a quicker version of the Radeon HD 7970M, itself a 2011 product, with a 50MHz higher Boost clock speed.
So, yeah, it doesn't look like AMD is breaking much new ground here. I'll keep an eye out for more details on the R7 M265, but I'm not holding my breath for something wildly exciting. (Thanks to TR reader Jorge for the heads up.)
