Mysterious AMD Radeon R7 250XE Shows Up

AMD's new entry-level graphics card to counter NVIDIA's GeForce GT 730/740, is the new Radeon R7 250XE, which has been showing up unannounced, in certain Japanese stores. Its reference-design card is pictured below, as having a low-profile, single-slot design. The card is said to be based on a refreshed, energy-efficient variant of the 28 nm "Cape Verde" silicon, featuring 640 stream processors, a 128-bit wide GDDR5 memory interface holding 1 GB of memory, and clock speeds of 860 MHz core, and 4.50 GHz memory. The card is being designed to capture the $60-$70 price-point.

isn't the current 250x already faster than the 740? unless this one is slower than the 250X

250x/7770 requires a 6-pin pci-connector. This looks to be AMD taking a full chip (which obviously gives best perf/w), yield-friendly clocking it for the lowest feasible clock ( .9v is the lowest feasible on 28nm, which would save power and yield that clock on avg, but could be higher higher voltage and just bad chips) and similar lowest power-efficient with ram/mem controller; keeping it under 75w. Either super low leakage or super-crappy clocking/v...whichever.

It would be much more interesting if they did it with Bonaire (896sp) at similar clocks or up to 925/5000, but obviously that must not be practical (it must be close though)....or coming later.

Think similar to what they did with 270 and 150w, and perhaps what they may do with certain Tonga parts at (150?/)225w. I would seriously laugh if AMD could get a ~860-925/4400-5000 1792sp part to fit under 150w (which seems technically possible)..what would be the competition, 750ti?

I like that they are starting to go this route again as options, even if obscure parts. More units @ power efficient clocks/voltage shoe-horned under a certain pci-e spec is always better than any other alternative within that same spec. Last time I remember them really going full bore in the mainstream lineup using that philosophy was 4850, aka probably the best value part ATi (intentionally) made (Thank Dave Bouwman for that one iirc).

I was thinking the same thing.

looks nice for basic but small fan may give you more noise

my R7 240 from MSI is pretty much silent (it's on my table near my TV with no case around and clocked 950/1000) 40° max in Valley (for the fun) and a bit more louder tho bearable


ok the fan might be a bit better than the one we have on the R7-250xe ref xD

I see another site that's showing a label/package indicating 1000Mhz (but that box looks a little strange) If that's the case and no 6-pin it would be very odd for the Cape Verde to ante-up such a clock. Just a thought, could AMD had this re-spun at GloFo? Perhaps? Sure the processes don't exactly allow straight transfer, while why would they keep Cape Verde naming. Or is that what author(s) are putting to it as it is still offering those same spec's. Could AMD just taped out the same chip and getting GloFo process efficiencies with better pricing?

it's just a R7 250X with lower clock (860MHz core, 4500MHz memory)

Yea appears someone did some funny work the photo perhap on that other site same picture but showing 1000Mhz.
There had been some 7750's with the 850Mhz/4800 MHz effective that didn't need 6-pins, so this is all it appears to be. But don't recall any 7750 in Low Profile with OC specs so this is kind of different...

This should be a great alternative to the m-itx HTPC systems as this would be great for movie viewing on a big screen and low clearance and extreme power conservation.. Looks like a win for Radeon.:peace:

I would love to see a PCI-E 1x version of this like there is for the GT 610 and 510.
