Intel has a LOT of lake variants and for someone like me its kind of hard to understand what's going on, I think Alder Lake is 12th gen but how exactly is it better and how is it different from rocket lake and tiger lake. Also would be great to know what letters at the end of CPU names represent what lake. Thanks

Alder Lake is basically general improvements + extra small cores on top of Tiger Lake which only gets 4. Rocket Lake is basically Tiger Lake's design with double the core count and 14nm

They don't, the letters only represent whether the CPU has iGPU disabled, multiplier unlocked, 5w or 15w (default) or neither base power limit.

The difference will be in the architecture optimization and clock improvement, which leads to better Instruction Per Clock (how many maths it can do per second basically) which leads to a more efficient CPU or a much faster one. To put it simply in a rule of thumb: the newer it is, usually the better the product is (but of course there is exceptions to the rule and you should still refer to reviews)

Its not in the letter, its in the numbers. Intel has made a consise guide to their CPU naming scheme.

What we are sure about is that Alder lake simply will come with more cores without effecting the single core performance of other cores. regardless how fast they are, but more cores means more performance as long as they don't effect other cores, but how much more performance depends on the kind of the workload that the application ask for.

 

For gamers more cores could mean more performance for very few games considering that more cores won't drop other cores performance with Big.Little design and could promise to be more future proof because newer games are being optimized to make use of more and more cores

 

What we are not sure about is whether Alder lake is going to be actually better than Rocket lake for gamers. Based on recent news Alder lake golden cove core performance is much much less than Intel expected it to be so it may not even be any better than Rocket lake and I don't really see that Alder lake is going to be any good to wait for or to consider. Even DDR5 won't be better than today's fast DDR4 modules at release time so it will take more time to get considerably more performance with DDR5.

 

For Laptops Alder lake would definitely be an improvement in everything over older generations, but for Desktop I doubt that Alder lake would be any better.
