Final Words 

In this review, we examined G.Skills' top TridentZ5 EXPO compatible kit to highlight the impact of frequency and performance scaling. Our initial expectations were that DDR5 memory in between 4800 MHz and 6000 Mhz would have made a huge difference. The story, I am afraid, is more complex. The combination known as sweet spot memories, when used in conjunction with Ryzen 7000, is unquestionably a good spot in terms of performance. I am inclined to recommend it at 75-100 USD more for this type of memory. But only if you are willing to pay more money on DDR5, latency is what matters, and this article should have demonstrated that CL30 at 6000 MHz is unquestionably quicker than, say, CL40 at 5200 MHz. Applications wise however, it's harder to notice. For gaming faster and more agile memory bandwidth helps.  There is a discernible difference between 4800 and 6000 MHz, but the price difference is also a thing. In short, latency is statistically more important than frequency. We ran out of time, but we'll add some results on 5200 MHz and super fast latency, as well as this raises the question of how valuable DDR5 at 6000 MHz is. Keep in mind, though, we tested with an enthusiast class GPU, with a more common graphics card, all these bigger differences will fade away, as the GPU is then the bottleneck. However, when we look at an RTX 3090 in gaming, we can observe that the frequency and, most critically, latency scale upwards. 





G.Skill does have a outstanding 6000 Mhz / CL30 memory kit available with the TridentZ5 NEO series, this memory kicks ass. However, the 250-300 EUR price tag makes it difficult to justify a purchase. Then again, pricing has already halved from the initial DDR5 release. At a sub 10 USD per GB, we can't complain. You get DIMMs with a lifetime guarantee and a programmable RGB system for that price. The TridentZ5 NEO series DIMMs are a powerful product series aimed at a very specialized set of people: those who want the uber-fast things at the upper end of the range and with a niche-designed PC, then enthusiast-class PC gamer. The new DDR5 standard allows for greater frequencies at lower working voltages but at the penalty of increased latencies. Given this, it is logical for G.Skill to provide a variety of DDR5 families and wide options to choose from. The tested CL30 6000 MHz TridentZ5 Neo yay or nay. We'll stick to the AMD recommendations. 5,200MT/s at CL40 or better will be enough; CL 36 is undoubtedly more recommended, and CL32/CL30 is fantastic but at a higher cost. In terms of performance, G.Skill delivers a renowned kit that, in our opinion, is worth the extra money over a similar-capacity 5,200MT/s set. Well, yes, but that's a question that only you, the end-user, can answer. Regardlessly, this is a fantastic memory kit to own, and yes, it's sweet spot memory when looking at gaming (but not all saying).
