This is the deeper dive of AMD’s V-Cache that we teased with our short latency article and we will be covering a little more on the latency front along with the bandwidth behavior of V-Cache and the performance of V-Cache SKUs. A Bit More on Latency If you…

This will be a short post about how Alder Lake’s ring behaves when E-Cores are active. With just P-Cores active, the ring runs at 4.7 GHz. But if anything is running on the E-Cores, the ring frequency drops to 3.6 GHz. This drop happens regardless of whether…

If you were like us and were surprised that AMD announced 3D V-Cache back in August and wondered how AMD would be able to pull this off, well, we have a teaser article for you today regarding V-Cache’s latency! The Latency There was much speculation about…

I’ll be blunt here, this part will seem like an anti-climax compared to Part 2 of this series but I hope to nicely wrap up this series with this as the conclusion piece of what we know about how the changes talked about in Part 2 have affected the performance…

While chronic GPU shortages dominate the current news cycle (exacerbated by a myriad of individual factors set to continue for the foreseeable future), the massive increase in power requirements for high-end graphics cards is just as newsworthy. These higher…

While most enthusiasts chase the absolute best performance at any cost, there are a few who use efficiency as their benchmark for a card’s attractiveness. It can be argued that the efficiency of a design – how effectively it utilizes the resources available…

Header Image credit goes to Martijn Boer. In the world of x86 CPUs there are two major players, Intel and AMD. However, there is one (well two but that will be expanded on later) other company that designs and produces CPUs that are fully compatible with…

Often using an older GPU means sacrificing visual quality or resolution—trade-offs that many may find to be unacceptable. Overclocking can help of course, but what if you want more?That, my friends, is what we are here to find out.

Author’s Note: Andrei Frumusanu from Anandtech has reached out in this Tweet to clarify how Anandtech does Core to Core latency testing https://twitter.com/andreif7/status/1373942191920406530?s=19 Now, the program we use for Core to Core testing was made…

Banner image credit goes to Fritzchens Fritz and his amazing die shots Recent AMD and Intel high performance CPUs implement an op cache that remembers decoder output and functions like a L0 instruction cache. Compared to the traditional L1i fetch and decode…

Previously, we looked at ARM and x86 and concluded high performance designs wouldn’t get a significant advantage by using either instruction set. That article focused narrowly on the respective ISAs, and assumed equal ecosystem and implementation goals. Today…

Zen 3 is one of the fastest CPU cores currently on the market; that isn’t up for debate.However, even the fastest CPU cores have bottlenecks and today we are talking about the bottlenecks that Zen 3 has and what AMD could improve with Zen 4. We gathered far…

For the past decade, ARM CPU makers have made repeated attempts to break into the high performance CPU market so it’s no surprise that we’ve seen plenty of articles, videos and discussions about ARM’s effort, and many of these pieces focus on differences…

Radeon driver 21.6.1 puts Hawaii and Fiji out to pasture. Why? At the height of 2021’s continuing GPU shortages, AMD has chosen a curious time to end support for a line of GPUs that while old—the Hawaii-based Radeon R9 290X launched in 2013—still manage to…

This is the 2nd article of a multi-part series, with the focus starting on image compression. I would heavily recommend reading the 1st article as it explores a part of the history of image compression, which leads to talking quite a bit about the basis of…

AMD’s Graphs of 6700 XT Performance: 3070 Beater? When AMD went live on March 3rd they showed the graph below: In and of itself, this is a typical “red bar graph” first-party AMD performance slide that we have become accustomed to in their launch events.…

This article has been a LONG time coming since our article on Rocket Lake, where we talked about core to core latency for the first time here on Chips and Cheese. This is a follow up article exclusively about core to core latency. The core to core latency…

In our current times, digital information is one of the most important facets of our society. We generate a lot of data, transport a lot of data, and store a large portion of that data. Managing such huge quantities of data is a large task: one that requires…

We’ve gotten used to measuring CPU cache and memory latencies, so why not do the same to GPUs? Like CPUs, GPUs have evolved to use multi-level cache hierarchies to address the growing gap between compute and memory performance. And like CPUs, we can use pointer…

It’s all very normal, but good journalism is trying to keep things objective in pursuit of the truth, to the benefit of our readers.Guys, gals, and non-binary pals, I think we just had one of those exciting moments.Today in this follow-up article, we will…
