The lowest “K” model of the Intel Arrow Lake CPU family benefits, like its predecessors, from a large number of cores. Unlike them, it doesn’t have Hyper Threading, but it doesn’t lag behind compute-wise, and the Core Ultra 5 245K is more efficient. However, it’s not enough to rival the Ryzen 9000s. Not at high performance. In medium workloads, typical of gaming PCs, however, the situation turns around. Read more “Intel Core Ultra 5 245K vs. AMD R5 9600X or… R7 9700X?”
A new CPU has taken the throne of absolute performance – the Intel Core Ultra 9 285K. Yes, it’s a tight race, it’s with higher power consumption and lower efficiency, but that’s a necessary tax to pay for that “absolute peak”. Sure, someone will gladly sacrifice that leadership in favor of better operating characteristics, but either way, the 24-core CPU is the one that sets the pace in compute tasks on a mainstream platform. In this case, it’s Intel LGA 1851. Read more “Intel Core Ultra 9 285K: #1 in multi-threaded tasks even without HT”
Intel Arrow Lake desktop CPUs have undergone a significant change on many levels. Aside from the new performance (P) and efficient (E) core architectures, they are now chiplet-based and have stopped using Hyper Threading, for example. At the same time, the power consumption is lower and the Core Ultra 7 265K CPU is often more power efficient compared to the competition. This even in games, which we haven’t seen before.

High gaming performance is something that is kind of expected from the AMD R7 9800X3D. Compared to its predecessor (R7 7800X3D), however, the cooling options have been greatly improved, paving the way for higher clock speeds. The R7 9800X3D has thus advanced especially in terms of multithreaded, but also single-threaded performance. This makes this CPU more versatile – better able to handle multiple usage scenarios.

You may not know this, but the x265 video encoder can use AVX-512, but they are unused by default for historical reasons. In the past we made a guide showing how to enable the optimizations and looked at their effect, first on Intel Rocket Lake processors and then on Zen 4. Due to the popularity of those articles, we’ve now repeated the same tests on the new Zen 5 architecture, for comparison with previous cores. Read more “How much does AVX-512 help Zen 5 in x265? And how to turn it on”
We’re wrapping up tests of the new Ryzen 9000 desktop CPUs. This with a model that once increased the number of cores compared to its predecessor, or a pilot model (Ryzen 9 3900X) from eight to twelve on AMD’s mainstream platform. Even compared to the Ryzen 9 5900X, the new Ryzen 9 9900X is more than twice as fast in some practical situations. This model is also the best when it comes to efficiency.

Not only maximum speed, but also maximum efficiency among AMD’s single-chiplet CPUs. That’s the essential characteristic of the Ryzen 7 9700X. While the speed difference from the last generation (and the Ryzen 7 7700X processor) is negligible, zero, or even negative in places, it comes with significantly lower power consumption. And for those who don’t appreciate it, BIOSes with higher TDP are available less than a month from release. Read more “AMD Ryzen 7 9700X: One chiplet (Zen 5) to the max”
The most powerful AMD Zen 5 CPU is the fastest not only multi-threaded (when all cores are involved), but also single-threaded. It usually beats the competing Core i9-14900K processor quite clearly. Although, this may not always be the case and there are situations where the 16-core Ryzen 9 9950X is weaker. I mean, speed-wise. The efficiency (due to the lower power consumption) may already be on its side. Read more “AMD Ryzen 9 9950X: At the very top, with both 1 and 32 threads”
In the first wave of new AMD processors with Zen 5 architecture, we took a closer look at a Ryzen 5. The results show many improvements (in speed, in efficiency, in cooling, …) led by unprecedented single-threaded performance. But in terms of the multi-threaded one, it’s still well behind the rival Intel Core i5-14600K CPU, albeit with much better power consumption. Gaming performance? Sometimes strange.

For completeness of Intel Core i5-14400F processor tests we add the results of its second stepping. We’ve already tested the B0 variant, now it’s time for the C0. Its availability in stores is, at least at the moment, considerably worse and the question arises whether it is worth it at all. Is there any point in aiming for stepping C0 or is B0 also “okay”? Or does it “not matter” (what you get in the shopping lottery)? Read more “The Core i5-14400F analysis is complete. Rare stepping (C0) tested”
It’s the fastest Core i3 yet, but it’s also the hungriest. The 14100F’s (Raptor Lake Refresh) biggest competition in its own ranks is in the form of older models (13100F and 12100F). These are a bit slower, but lower-power. The “better” choice depends on what holds more weight on your scales. Maybe it will be that record-breaking speed? In this class (Core i3), power consumption is always relatively low. Read more “Intel Core i3-14100F: Four cores whipped to the max”
Also on the list of lower-power Intel Raptor Lake Refresh processors with 65W TDP is the Core i5-14400F. That is, a model that, mainly because of its attractive price-performance ratio, often ends up in lower-budget PC builds. In the 14th generation, Intel sped up the single-core boost and also E cores. And there are more changes in the small details. For example, the fact that different steppings built on different silicon are again common in e-stores.

The top model of the 14th generation of Intel Core (Raptor Lake Refresh-S) processors has outperformed everything that has come out for desktop computers so far. In speed, but also in power draw. On the one hand, the 6 GHz metric for single-threaded applications has been reached and the clock speeds are very high even under all-core boost, the side effect is that the Core i9-14900K’s power draw can sometimes spike up to 400 W.

The Core i7-14700K processor is the only 125-watt model from the Intel Raptor Lake-S Refresh generation that has undergone a core configuration change between generations. With more “efficient” ones, this processor is halfway to the Core i9-(14900K/13900K), but at the price of a Core i7. The Ci7-14700K is thus significantly more powerful than the Ci7-13700K for the same money. Especially in heavy multi-threaded workloads. Read more “Intel Core i7-14700K: Four extra E cores can work wonders”
In the Raptor Lake Refresh generation, Intel has gone a bit harder and increased the clock speeds in the Core i5 class. This has led to higher application and gaming performance, but by pushing the manufacturing process to its limits, power draw has naturally increased, and with it comes poorer efficiency. The latter may not be that important for someone and the main thing is that the processor can be comfortably operated even with a “normal” cooler.
