Moving on, Tomb Raider looks good when set to high - and we can barely tell the difference between this setting and very high/ultra - though the framerate did drop to 30fps a couple of times. Still, it's largely smooth and eminently playable at 1080p on all cards. If you're wondering why the Asus 896-core card is routinely faster than the Gigabyte, it has to do with the former remaining at its 1,256MHz core speed at all times; the Gigabyte would oscillate between 1,100MHz and its rated speed of 1,212MHz.
We're using a collection of games that don't all need high framerates. Warhammer is one of those that fit into this camp. The RX 460s produce acceptable rates, with a minimum of 40fps, so this strategy game is another good fit for a card of this ilk, with both producing the same kinds of performance level. Note that cheaper FreeSync screens often have a 47-75Hz operational range, without the benefit of low-framerate compensation, so you will need to drop the settings to medium in order to achieve super-smooth gameplay.
Driving games need higher performance because of the obvious motion involved. Looking at a fairly recent title, Dirt Rally in this case, shows that a well-coded title doesn't need a super-high-end PC to run on. With a minimum of around 45fps on both cards, this is a posted child for FreeSync.
Strapping some cores on the engine via the BIOS flash gives the RX 460 a needed boost to beat out a well-overclocked GTX 1050. You're getting a tad more performance and double the framebuffer for the same outlay.
