It looks like AMD is set to reveal at least one more graphics card before the year is up, with the latest rumors suggesting the company will launch the Radeon R9 380X at the end of next week.

The R9 380X is expected to be one of the first non-Fiji-based graphics cards to be released this year from AMD that's not a simple re-brand of an existing GPU. The card will reportedly feature a fully-unlocked Tonga GPU, giving it more stream processors and better performance compared to the two existing Tonga-based cards, the R9 380 and R9 285.

Thanks to the card's use of a full Tonga GPU, the R9 380X will feature 2,048 stream processors, 128 TMUs and 32 ROPs. Clock speeds haven't been confirmed just yet, although it's expected that the card will run at around 1,000 MHz on the core, and at least 5,500 MHz on the memory.

Speaking of memory, the R9 380X is set to be equipped with 4 GB of GDDR5 memory on a 256-bit bus, providing at least the same bandwidth as the R9 380 (176 GB/s). There's no word on how much power the R9 380X will consume, though you'd expect its TDP to come in slightly higher than the R9 380's 190W.

According to the rumor, the R9 380X will launch on November 15th and will cost around $249, making it $50 more expensive than the R9 380, but cheaper than the $300 R9 290. This is all just a rumor at this stage, so take it with a grain of salt, but it wouldn't be a huge surprise if AMD launches a card at this price point.
