AMD has released four new processors that improve performance, system responsiveness, and power efficiency.
AMD has launched its 2nd Generation Ryzen processors. They are based on a refined update to their Zen architecture that is being called Zen+. The 2nd generation Ryzen processors offer higher clock speeds, lower latencies, and a more intelligent algorithm that not only improves performance, but also system responsiveness and power efficiency.
The new CPUs use the same AM4 infrastructure as the AMD 1st generation processors and are compatible with the same socket, chipsets, and motherboards; they just require a BIOS/UEFI update.
The two Ryzen 7 processors that were released are the AMD Ryzen 7 2700X and the AMD Ryzen 7 2700. The Ryzen 7 chips are 8-core CPUs with 20MB of cache that top out at 4.3GHz.
The two Ryzen 5 processors that were released are the AMD Ryzen 5 2600X and the AMD Ryzen 5 2600. The Ryzen 5 chips are 6-core CPUs with 19MB of cache that top out at 4.2GHz.
AMD claims that the 2nd Generation Ryzen processors offer reductions in cache latencies of an impressive amount: 13% in L1, 34% in L2, and 16% in L3, respectively. Memory latency is also reduced by about 11%.
Of course, CPU caches are the bread and butter when it comes to CPUs, so any improvement in speed is fantastic.
CPU caches are small memory pools that store information the CPU is most likely going to need next. The goal of the cache system is to ensure that the CPU has that next bit of data that it will need already ready by the time it needs it.
For instance, if I wanted to make pancakes and went in to the kitchen to find my spouse waiting with the bag of pancake mix already in her hand, that would be how the L1 cache works.
Now, if I went into the kitchen and found that, sadly, my wife wasn’t in the kitchen with the pancake mix ready, but instead we had to open the cabinet over the stove to find it, that’s how the L2 cache works.
Long pancake story short, if the L1 doesn’t have the data that the processor needs ready, it looks to the L2, if the L2 doesn’t have it either, it moves to the L3. So, having speedy caches makes faster pancakes… I mean improves processor power.
