CPU, New Tech, Packaging, and Test Setup
AMD Marketing Points
AMD had several slides in their presentation for the new Ryzen 3 models, but since we can share our results, we will skip those provided by AMD. However, it is worth noting as you see here that AMD, with its Ryzen lineup, has shaken things up a bit over the years since its introduction. AMD has, in a way, pushed what was quickly becoming a stagnated offering into more performance per dollar options being available thanks to competition.
Both CPUs, as you can see here, are quad-core parts with SMT for a total thread count of eight. They both carry a 65W TDP and are 7nm chiplet-based units. This does mean that we can expect the same architectural improvements and performance we have come to expect from AMD's 7nm based CPU parts.
The 3300X is specified with a 3.8GHz base and a maximum boost of 4.3GHz. The onboard 18MB "Game cache" or combination of 16MB L3 combined with 2MB L2 is a powerful addition to boost gaming and other performance metrics.
The 3100 CPU comes in with a base clock of 3.6GHz and a maximum boost of 3.9GHz. Now that clock speed will make a significant performance differential in out of the box performance. But, I do think that with a proper OC, we can make up for some of this.
There is one area that will not be able to be mitigated by the user, and this is the die layout itself. With AMD's 7nm chiplets, one chiplet is called a CCD (core chiplet die) and contains two core complex units containing up to four cores each. So, when you see a 7nm chiplet, keep in mind that while it may be one package with up to eight cores, it is a single die containing two core complexes with up to four cores each. Now the 3100 and 3300X are built differently as the CCX is deployed in different ways. The 3100 goes with two cores per CCX, for two cores and four threads per CCX. The 3300X employs a single full CCX for the four cores and eight threads.
The reason this is important is that the cache is essentially split in half for the 3100, which has half of the cache on one CCX, and the other half on the other CCX. This means that the unified cache and latency when a core needs to grab something or talk to the other cache or pair of cores, there will be induced latency. This latency will be felt via a reduction in performance.
My testbench is strictly controlled with a fresh OS for any platform or component change. The system uses all the same components whenever possible to maintain comparable results between platforms. The ambient in the test lab is rigorously controlled at 22C +/- 1C. All tests are run a minimum of three times, and any outliers are tossed, and another replacement test run will be completed to achieve our average results.
The use of a TITAN RTX for the CPU testing is to ensure that the GPU is not the bottleneck for performance results, and will best represent the scaling across CPU and platforms.
