Rumors on AMD's next high-end GPU, tentatively called Radeon RX 490, surfaced online after a recent benchmark sighting using the Standard 1080p present in DirectX 12.
An unannounced AMD graphics card has been revealed on the Ashes of the Singularity benchmark database, which is comparable to the new AMD flagship Radeon RX 490 graphics card.
According to WCCFTech, four benchmarks were conducted with DirectX 11 API mode, consisting of Crazy, Standard and Low settings. However, the Standard 1080P DX 12 test was the one compared against other GPUs' performance.
Based on the said sighting, the results listed for the purported AMD Radeon RX 490 is for the standard 1080P DX 12, which showed a staggering 8,400 points - a value on par with its NVIDIA rival GeForce GTX 1080. The latest benchmark score was listed at 131th position before it was deleted, indicating that the result was not supposed to be shown to public.
As per its internal chassis, Radeon RX 490 is expected to be a dual-GPU card based on Vega architecture, since RX-490 is a high-end entry in AMD's Radeon lineup, and Vega GPU family is built to feature high-end members.
Previous reports suggest that the Radeon RX 490 will also include 8GB or 16GB of HBM2 on-board memory - a memory bandwidth of up to 512GB per second - and 4,096 processors packed into 64 Compute Units, Digital Trends has learned. The next gen GPU will even provide 24 TFLOPS of half-precision performance, and 12 TFLOPS of single-precision compute performance.
Based on some hints, AMD might release a PRO version of the RX 490 for the Mac and MacBook Pro lineup that are expected to be released in the coming future, a feature that should boost performance on Apple's laptop.
AMD is positioned to host its "New Horizon" event to display live demos of its "Zen" processor architecture and the first "Summit Ridge" desktop CPUs. Latest rumors indicate that the company will reveal the Radeon RX 490, Pro 490 graphics cards and the AM4 X370 Zen Motherboard that will support the Summit Ridge chips in the said event.
