AMD Navi 14 could be obtainable in 5 variants, a Linux driver entry suggests.

AMD Navi 14 XTX, XT, XL XLM, XL

Inside the agd5f/linux repository yow will uncover a model new entry with 5 Navi 14 GPU variants listed. Let’s look nearer at this data.

The clocks

A number of of you won’t be accustomed to a time interval of a peak clock. It is a definition of the perfect achievable frequency for a specific GPU. For Vega Frontier, the marketed improve clock was truly further a peak clock. This, nonetheless, has modified for Navi period, as peak clock was primarily renamed to improve clock, and one factor that is typically commonly known as a improve clock is now known as a sport clock. I do know, it is pretty difficult.

For Navi GPUs, tech journalists are more likely to check with an actual-in-game clock as a improve block (Navi’s Sport Clock). It is nonetheless not pretty the equivalent as NVIDIA’s Enhance Clock (which is usually lower than the exact clock), however it merely matches larger with any comparisons. For Navi period, the exact frequency sits between the marketed sport clock and improve clock (check this TPU review for instance).

The GPUs

As you most likely already know Radeon RX 5700 assortment choices three completely totally different GPU variants: XTX, XT, and XL. The XTX variant was not publicly marketed (even after the evaluations went reside). Nonetheless, we confirmed that XTX is reserved for 5700 XT 50th Anniversary SKU.

The most recent entry throughout the Linux repo moreover lists the XTX variant for Navi 14, nevertheless at this degree, it’s mindless to anticipate a 50th anniversary SKU for the RX 5500 SKU. We moreover know that the XT variant is already in the RX 5500.

That acknowledged, an knowledgeable guess might be to anticipate Navi 14 XTX with Radeon RX 5500 XT, which was already seen in some places, resembling EEC entries:

GV-R55XTOC-8GD,GV-R55XTGAMING-8GD,GV-R55XTWF2-8GD,GV-R55XTD6-8GD

As you can see, the GPU variant naming schema is a bit of bit of a giant quantity. These are sometimes not used for promoting (for obvious causes), nevertheless they’re very useful for decoding the goal of the GPU. Please do not cope with this chart as a tenet, that’s merely an illustration of the popular ones.

It’s normally worth noting that Navi 14 XTX may be outfitted with further cores, as solely 22 CUs are enabled on the XT variant. The entire silicon has 24 CUs:
