Leaked Radeon RX 5600 XT benchmarks reveal memory OC scaling

When AMD announced its Radeon RX 5600 XT, our initial thoughts were that this graphics card could be a strong overclocker, especially when it came to the GPU's memory speeds. 

Today, new 3DMARK Fire Strike benchmark scores have been leaked, via _rogame, which reveals a correlation between the Radeon RX 5600 XT's benchmark performance and memory overclocking, proving that the GPU is memory-limited in specific applications. 

What's worth noting here is that these are 3DMARK Fire Strike scores; and that 3DMARK Fire Strike is an old benchmarking utility which runs at 1080p under DirectX 11. As 3DMARK Fire Strike is an older 1080p benchmark, memory bandwidth shouldn't be a significant constraint on the Radeon RX 5600 XT's performance, which means that higher resolutions, such as 1440p, could be more performance constrained by AMD's chosen memory configuration. Newer games would also be more memory-constrained by the Radeon RX 5600 XT's 12Gbps memory and 192-bit memory bus. 

When looking at the Radeon RX 5600 XT's 3DMARK Fire Strike Graphics scores, we can see that using 14Gbps GDDR6 memory speeds yields a 6.72% boost in performance while using 14.4Gbps memory speeds delivers a 7.5% boost in graphics performance. These results come thanks to 16.7%, and 20% boosts to total memory bandwidth/clock speeds, respectively.

Why is the Radeon RX 5600 XT memory limited? 

If the Radeon RX 5600 XT is memory limited, why isn't AMD shipping the graphics card with faster GDDR6 memory modules? Wouldn't that help AMD compete with Nvidia's higher cost graphics cards? 

The simple answer to this question is pricing and product segmentation. Using faster GDDR6 memory would bring the Radeon RX 5600 XT closer to AMD's Radeon RX 5700, making it a less appealing purchase. On top of that, higher-speed GDDR6 memory would add more cost to AMD's budget-friendly Radeon RX 5600, a move which would bring the graphics card closer to the RX 5700 in terms of pricing and performance. It makes little financial sense for AMD to do that. 

Hopefully, Radeon RX 5600 XT users will be able to overclock their Radeon RX 5600 XT graphics cards to 14Gbps to regain some of this lost performance potential. However, this depends on the quality of the GDDR6 memory modules on your specific graphics card. Even so, memory overclocking may still be the first port of call for Radeon RX 5600 XT overclockers.

Leaked Radeon RX 5600 XT benchmarks reveals memory OC scaling  

AMD's Radeon RX 5600 XT is designed to surpass Nvidia's GTX 1660 Ti graphics card, solidifying AMD's hold on the sub-$300 GPU market. Hopefully, this graphics card's pricing will translate well in the UK and Europe.

What is with the naming of AMD's GPUs?... RX 5600 XT? Why not just go simple; RX 5600 or 5600 XT?...Quote

Maybe hints at quite a few SKU to be released so many variations to hit the market. The naming from both brands are a bit out of control in my eyes. Or at least the manufacturers are going loopy over it.

MSI Gaming X Trio RTX 2080ti..

RTX alone should have led to a reset in model naming.
RTX 1.x



God just imagine it... MSI Gaming X Trio RX5600 XT just why?!Quote

There is an RX 5600, but it's just for OEMs. Just like the RX 5500. There will also be an RX 5600M product for mobile.Quote

Well then, why not just make it short and logical then?:

RX 5600O (OEM)
RX 5600C (Consumer)
RX 5600M (Mobile)Quote
