AMD's highly anticipated R9 300 series are expected to be unveiled on June 16, 2015, which happens to be the date when the world's premier trade show for computer, video games and other related products kicks off. Now, according to Sweclockers, the launch price of the upcoming series is going to be far more expensive as compared to launch price of R9 200 series. However, one thing that the desktop and graphics processor manufacturing company has done is increased the standard memory capacity on its high-end card lineup from 4 GB to 8 GB.

Since PC titles are becoming far more demanding and will require a ton of video frame buffer to deliver smoothed-out gameplay sessions at high resolutions, it is a commendable thing done by AMD, assuming the information turns out to be true. While prices were detailed in the Swedish Krona currency, they have been converted into USD for a more accurate comparison against NVIDIA's GTX 900 series. Details of each card and its price have been stated below:

• Radeon R9 390X 8 GB: 4,990 SEK ($499)
• Radeon R9 390 8 GB: 4,190 SEK ($419)
• Radeon R9 380 4 GB: 2,790 SEK ($279)
• Radeon R9 380 2 GB: 2,490 SEK ($249)
• Radeon R7 370 4 GB: 2,090 SEK ($209)
• Radeon R7 370 2 GB: 1,790 SEK ($179)
• Radeon R7 360 2 GB: 1,390 SEK ($139)

The biggest price difference is between R9 390 and R9 380. R9 390 is expected to deliver performance in between the capabilities of GTX 970 and GTX 980. One the other hand, R9 390X is going to provide PC gamers with performance that will land in between GTX 980 Ti and GTX 980. AMD is yet to unveil the direct competitor of NVIDIA's current single flagship GPU solution, GTX Titan X, which features 12 GB of GDDR5 type memory.

As stated earlier, the R9 300 series are expected to be showcased during E3, 2015 and with that, accurate pricing and hardware specification details will be made available to the globe.
