With the exception of the R9 290X, the R9 290, and the R7 260X, AMD's recent branding campaign with the Radeon R7 and R9 series of graphics cards is really just a reorganization and rebranding of existing parts. When we reviewed the Radeon R9 280X and R9 270X, both were well known entities though this time with lower price tags to sweeten the pot.
Today, AMD is continuing the process of building the R7 graphics card lineup with the R7 250X. If you were looking for a new ASIC, maybe one that includes TrueAudio support, you are going to be let down. The R7 250X is essentially the same part that was released as the HD 7770 in February of 2012: Cape Verde.
AMD calls the R7 250X "the successor" to the Radeon HD 7770 and its targeting the 1080p gaming landscape in the $99 price range. For those keeping track at home, the Radeon HD 7770 GHz Edition parts are currently selling for the same price. The R7 250X will be available in both 1GB and 2GB variants with a 128-bit GDDR5 memory bus running at 4.5 GHz. The card requires a single 6-pin power connection and we expect a TDP of 95 watts.
Here is a table that details the current product stack of GPUs from AMD under $140. It's quite crowded as you can see.
|Radeon R7 260X||Radeon R7 260||Radeon R7 250X||Radeon R7 250||Radeon R7 240|
|GPU Code name||Bonaire||Bonaire||Cape Verde||Oland||Oland|
|Rated Clock||1100 MHz||1000 MHz||1000 MHz||1050 MHz||780 MHz|
|Memory||2GB||2GB||1 or 2GB||1 or 2GB||1 or 2GB|
|Memory Clock||6500 MHz||6000 MHz||4500 MHz||4600 MHz||4600 MHz|
|Memory Bandwidth||104 GB/s||96 GB/s||72 GB/s||73.6 GB/s||28.8 GB/s|
|TDP||115 watts||95 watts||95 watts||65 watts||30 watts|
|Peak Compute||1.97 TFLOPS||1.53 TFLOPS||1.28 TFLOPS||0.806 TFLOPS||0.499 TFLOPS|
The current competition from NVIDIA rests in the hands of the GeForce GTX 650 and the GTX 650 Ti, a GPU that was released itself in late 2012. Since we already know what performance to expect from the R7 250X because of its pedigree, the numbers below aren't really that surprising, as provided by AMD.
AMD did leave out the GTX 650 Ti from the graph above... but no matter, we'll be doing our own testing soon enough, once our R7 250X cards find there way into the PC Perspective offices.
The AMD Radeon R7 250X will be available starting today but if that is the price point you are looking at, you might want to keep an eye out for sales on those remaining Radeon HD 7770 GHz Edition parts.

The next generation of AMD graphics processors are being announced this afternoon. They carefully mentioned this event is not a launch. We do not yet know, although I hope we will learn today, when you can give them your money.
When you can, you will have five products to choose from:
- R7 250
- R7 260X
- R9 270X
- R9 280X
- R9 290X
AMD only provides 3D Mark Fire Strike scores for performance. I assume they are using the final score, and not the "graphics score" although they were unclear.
The R7 250 is the low end card of the group with 1GB of GDDR5. Performance, according to 3DMark scores (>2000 on Fire Strike), is expected to be about two-thirds of what an NVIDIA GeForce GTX 650 Ti can deliver. Then again, that card retails for about ~$130 USD. The R7 250 has an expected retail value of less than < $89 USD. This is a pretty decent offering which can probably play Battlefield 3 at 1080p if you play with the graphics quality settings somewhere around "medium". This is just my estimate, of course.
The R7 260X is the next level up. The RAM has been double over the R7 250 to 2GB of GDDR5 and its 3DMark score almost doubled, too (> 3700 on Fire Strike). This puts it almost smack dab atop the Radeon HD 6970. The R7 260X is about $20-30 USD cheaper than the HD 6970. The R7 is expected to retail for $139. Good price cut while keeping up to date on architecture.
The R9 270X is the low end of the high end parts. With 2GB of GDDR5 and a 3DMark Fire Strike score of >5500, this is aimed at the GeForce 670. The R7 270X will retail for around ~$199 which is about $120 USD cheaper than NVIDIA's offering.
The R9 280X should be pretty close to the 7970 GHz Edition. It will be about ~$90 cheaper with an expected retail value of $299. It also has a bump in frame buffer over the lower-tier R9 270X, containing 3GB of GDDR5.
Not a lot is known about the top end, R9 290X, except that it will be the first gaming GPU to cross 5 TeraFLOPs of compute performance. To put that into comparison, the GeForce Titan has a theoretical maximum of 4.5 TeraFLOPs.
If you are interested in the R9 290X and Battlefield 4, you will be able to pre-order a limited edition package containing both products. Pre-orders open "from select partners" October 3rd. For how much? Who knows.
We will keep you informed as we are informed. Also, the announcement is still going on, so tune in!
