Welcome 7nm, AMD NAVI is here! – AMD Radeon RX 5700XT and RX 5700 Graphics Card Review

Does PCIe 4.0 help the RX 5700 series?

Here We will test a few of our benchmark suite to see if there is any real difference in performance being on the new PXIe 4.0 X570 Platform.

Shadow Of The Tomb Raider

Now we’re getting into the territory of a game more optimized for the higher performance GPUs. Shadow of the Tomb Raider is an awesome game and part of a long lasting franchise. It supports full DX12 along with new RTX features which we may start to include in testing once Radeon options have ray tracing capabilities enabled. We run at max details at DX12 with RTX and DLSS disabled.

First up is an actual game. Shadow of the Tomb Raider shows that any graphical performance swapping to PCIe 4.0 is within the margin for error at best. This tells me something that I suspected which is that the GPUs simply do not have enough bandwidth needs to show any performance gains at least at this time. I’m sure we will get there but time will tell as tech evolves.

3DMark Fire strike

3DMark Firestrike Ultra shows a gain for the RX 5700 while the RX 5700 XT actually lost some steam at PCIe 4.0. I can only assume this is standard testing variance at play and once again call it more proof in the pudding.

3DMark Time Spy

Time Spy Extreme is more of the same. The RX 5700 shows no change at all, with the exact same graphics score. The RX 5700 XT shows an extremely minor gain and within a close enough margin that I would not call it a reason to need PCIe 4.0 for these cards.

The numbers don’t lie, while it’s cool to have PCIe 4.0 on the platform, it simply will not net you much as far as GPU performance gains. SSD/Storage and other devices such as network and HBAs I could see a major advantage to the new interface. But You would be safe to grab an RX 5700 series for any of your current PCIe 3.0 based platforms and you will not suffer any measurable performance loss.

Undervolting the RTX 3080 and the RTX3090

What if you could find a way to lower both the temperature and the power consumption of your new GPU while still getting almost the same performance? Well, there is. It is called undervolting. Since the RTX 3080 and RTX 3090 came out there has been a lot of talk about undervolting them to get better thermals while still getting kick-ass performance and of course I decided I wanted to try it out myself. In the following pages you can both read on how to do it yourself but also get an idea how it will affect both the performance but also the thermals (and noise level).


  1. Stauros Scorpion

    Hot and loud and performance is ok but not great.

    • It was truly not very hot or loud in my experience. I have seen some who have reported that issue but my card under gaming loading never got anywhere above expected GPU temps. I do wish it had more headroom, but we will find out as WATTMAN was still pretty sketchy when we got a last-minute driver to test it.
