The new GTX Titan X is based on the same Maxwell architecture as its market leading sibling, the GTX 980. In terms of specs the Titan X is basically one and a half GTX 980s with 50% more CUDA cores, 50% more texture units and 50% more transistors. Comparing the performance profiles of the GTX 980 and Titan X shows that the Titan X leads by 36% which is broadly proportional to its improved hardware specs. With performance up by 36% and prices up by nearly 100% the Titan X is a hard sell from a value perspective. Two GTX 980s cost roughly the same as one Titan X and in SLI outperform a single Titan X by around 50%. The Titan X obviously isn't aimed at value conscious buyers but if you are in the market for the fastest single consumer graphics card money can buy, then the Titan X will hit the spot perfectly.

The AMD R9 390X is a rebadged power hungry (350W+) 290X. The 390X has a slightly increased GPU clock speed, a significantly increased memory speed and a higher minimum VRAM of 8GB but it shares the same core GPU hardware. Looking at the overclocked performance differences between the older 290X and the 390X shows that the two cards are approximately the same, which comes as no surprise considering that the 390X is actually just a factory overclocked 290X. Smart shoppers obviously won't be happy to pay AMD a premium of around $100 simply for overclocking a two year old 290X. That said the 390X does offer stellar performance, particularly at 4K resolutions and if prices drop significantly it could become a strong contender. We only have one MSI sample benchmark for the 390X so far so we will revisit this GPU when we have a better sample of all the available cards. [Jun '15GPUPro]
