See I really like talking about all this but reading it through and thinking how many are going to be lost. Just for others reading then who maybe are not generally into the tech but this may help with the jargon being stated between us all.
With regards to RAM both AMD & Intel support RAM overclocking with pre-installed settings which for AMD are known as AMP and for Intel are known as XMP.
To use these settings you need to go into the Bios and select the profile that matches to your RAM chip. This often just needs to select enabled and it will select the one that matches your RAM.
Now with that in basics, currently AMD requires them to test all the boards and RAM chips and provide validation codes to the board manufacture to then implement them. This has meant that at the moment the Bios are very much still being updated with these and they are causing the issues the last few posts have been discussing.
Intel on the other hand don't require this so it is just down to the board manufacture to sort themselves and it works much better as it is a lot faster to implement.
This then becomes important as the R7 series from AMD are actually two 4 core cpu's glued together via a method AMD are calling infinity fabric. Now this is important as infinity fabric relies on the speed of RAM to make sure that connection is fast enough to work properly and not cause a bottleneck.
For every 20% increase in RAM speed we see a 10% increase in the Infinity fabric link speed.
The reason the issue is so obvious is that the bios for all different boards from even the same manufacture are at different levels and so we are not seeing consistent RAM speeds being attained on the same setups. What I have suggested though is that with relatively little tweaking now that at least one board, the Asus Crosshair 6. Now I don't particularly rate Asus and their products, I feel they are overpriced and normally gimmicky.
A round up of other motherboard manufacture
- ASRock are great though and certainly like to push things from previous experience.
- MSI I avoid as their CS is the worst, even more so than Asus now and that says a lot.
- Gigabyte seem to cut corners although overall I haven't had an issue they are heading the Asus way which isn't good.
- Trying to get a hold of Biostar is difficult but they genuinely seem to do their own thing with items such as the first to show their smaller ITX boards (literally motherboard size for people who don't follow tech).
With all of that said above and everything else so far I would say you will see in real world zero fps difference between most of these CPU's.
