When E cores are disabled: Core i5-13400F vs. Core i5-12400(F)

Extra tests, Processors | | Ľubomír Samák

With the little (E) cores turned off, the Core i5-13400(F) becomes a 6-core processor with 12 threads in the same way that the older Core i5-12400(F) is. This intergenerational comparison is also a side product of tests main goal of which is to show the impact of E cores not only on computational and gaming performance, but also on operational characteristics. The biggest differences occur in the situations that mainstream PCs run into most often. Read more “When E cores are disabled: Core i5-13400F vs. Core i5-12400(F)” »

Not every Core i5-13400F is the same: Raptor (B0) vs. Alder (C0) lake

Extra tests, Processors | | Ľubomír Samák

In the vast majority of Intel Core i5-13400F processor tests (including ours), you’ve studied the results of the variant built on the Golden Cove cores from the Alder Lake generation. But there is also an iteration from Raptor Lake (with Raptor Cove cores). However, this processor is harder to get hold of, its availability is considerably weaker, but it is obtainable. You’ll find out if it’s worth the extra effort from the comparative analysis. Read more “Not every Core i5-13400F is the same: Raptor (B0) vs. Alder (C0) lake” »

24GB/48GB DDR5 modules don’t work with Ryzen CPUs, fix coming?

Memory, News, Processors | | Jan Olšan

In the past, Intel processors could not run newer higher-capacity DDR2 and DDR3 modules, while AMD processors worked. That’s why we were sort of assuming that the currently appearing DDR5 modules with unusual “non-binary” capacities would just automatically work on AMD platforms. But that’s not true, it seems that they only work with Intel processors for now and Ryzen 7000s will only be able to use them after a future update.

Ryzen 7000X3D: technical details and asymmetric CCX handling

News, Processors | | Jan Olšan

Last day of February, AMD started selling the Ryzen 7000 processors with 3D V-Cache, the chiplet technology increasing L3 cache capacity. Prior generation (Ryzen 7 5800X3D) proved that this benefited gaming, and it looks like the same is true now. Ryzen 7000s are aimed specifically at gaming PCs, and according to reviews, they seem to have surpassed Intel’s Raptor Lake processors in that and are now holding the gaming performance crown.

Intel LGA 1851 platform details: Z890 and Meteor Lake connectivity

Motherboards, News, Processors | | Jan Olšan

Intel LGA 1700 desktop platform is now running on its second generation of processors (Raptor Lake) which will see a refresh in fall, but that will be the end of this socket. A new LGA 1851 socket is planned for Meteor Lake and Arrow Lake processors and a report has now revealed new features of this platform. Intel will give the processor-connected I/O interfaces an upgrade that will put it closer to the AM5 platform. Read more “Intel LGA 1851 platform details: Z890 and Meteor Lake connectivity” »

Not just Meteor Lake. Even TSMC-made 3nm Intel chips are delayed

News, Processors | | Jan Olšan

There was a report that Intel allegedly cancelled the desktop version of the first 4nm Meteor Lake CPUs, which could indicate that the process is having issues similar to the early 10nm technology – like not reaching high enough clock speeds. But that may not be the only blow to Intel’s upcoming products. Now there are reports that even the 3nm chips, ironically enough those that it plans to outsource to TSMC, may be delayed as well.

Intel Meteor Lake to be mobile only, desktop 4nm CPUs cancelled

News, Processors | | Jan Olšan

Intel is now trying to catch up to TSMC and regain the manufacturing process leadership that underpinned its past dominance. So perhaps the biggest question for years to come is whether it has already managed to “fix” its factories, or whether processor delays and missed targets will be a recurring theme in the future. Warning sing are appearing that the first 4nm Meteor Lake processors could possibly end up like the notorious 10nm chips.

Ryzen 9 7950X: AMD’s elite CPU beats but also doesn’t beat Core i9

Extra tests, Processors | | Ľubomír Samák

We saved our tests of the most powerful Ryzen 7000 processor for last, for a number of reasons, as the last “X” model to expand the results database from this generation. The Ryzen 9 7950X, with its 32 threads, stands up to its 32-threaded competitor in the form of the Core i9-13900K with sovereignty, despite having eight fewer cores. Some might even state that it is the more cost-effective processor. But it comes down to your own point of view. Read more “Ryzen 9 7950X: AMD’s elite CPU beats but also doesn’t beat Core i9” »

Intel Core i5-13400F: Best price/perf ratio, questionable for games

Extra tests, Processors | | Ľubomír Samák

Thanks to the addition of E cores even in the lowest Core i5 Raptor Lake models (13400F and 13400), the raw performance between generations has advanced the most in years. However, the improvement may not always happen, the relatively small number of performance ones (P) combined with the lower Turbo Boost 2.0 clock speeds some games don’t like, and when they reach for E cores, the concept of big.LITTLE is at once detrimental.

Fact check: AMD is not limiting shipments to inflate prices

News, Opinion, Processors | | Jan Olšan

Last week, news stories have emerged that AMD is artificially inflating prices of its processors or GPUs by deliberately underselling the demand. This news has spread a lot. And yet, the report is almost certainly nonsense born out of misinterpretation (or misunderstanding of economics). There’s already been an official denial issued, but the story keeps spreading, so we feel it’s appropriate to address it a bit.

Intel Core i3-13100F: Tailor-made for cheap gaming builds

Extra tests, Processors | | Ľubomír Samák

Within the Raptor Lake-S CPU segmentation, it belongs to the lowest class (Core i3), but at the same time it is the fastest 4-core processor at all. AMD hasn’t had anything that directly competes with the Core i3-1x10xF processors in this segment for quite some time. So Intel, alone in the field, is pushing these processors in small steps, and the Ci3-13100(F) is already a very well “polished” foundation for budget gaming PCs.

AMD Ryzen 7 7700X: More efficient, but much weaker than Core i7

Extra tests, Processors | | Ľubomír Samák

It clearly outperformed its predecessors (including the R7 5800X) and also the Core i9-10900K, which has two more cores. But it can’t compare with the Core i7-13700K in heavy MT workloads, and that’s just a month after its release. In ST loads, however, it’s even performance-wise, as in games, where Ryzen 7 is more efficient. Whether the R7 7700X is worth more than the Ci7-13700K for similar money, however, you’ll have to judge for yourself. Read more “AMD Ryzen 7 7700X: More efficient, but much weaker than Core i7” »

Ryzen 5 7600: Raphael in AMD’s most popular series scores again

Extra tests, Processors | | Ľubomír Samák

This time, it wasn’t as long a wait as for the Ryzen 5 5600. On the contrary, the Ryzen 5 7600 came out very shortly after the faster model with the “X” in the name. AMD apparently hurried with this lower-power model also because of dissatisfied reactions that 7600X criticize the worse cooling. With the significantly more efficient R5 7600, the situation with silicon is brighter. Plus it’s cheaper and doesn’t lose all that much in performance.

Intel Lunar Lake: new “Conroe moment” processor revolution?

News, Processors | | Jan Olšan

A brand new CPU core architecture coming out is a big thing in the world of processors. We’ve been anticipating that from Intel for a long time, particularly in the Skylake era of waiting for 10 nm. Intel has since fielded new architectures in Ice Lake and Alder Lake, but there could be a major architectural revolution in a few years. The chips following Meteor Lake and Arrow Lake are said to be brewing something completely new. Read more “Intel Lunar Lake: new “Conroe moment” processor revolution?” »

AMD Ryzen 7000X3D release date revealed? (Update: Sadly not)

News, Processors | | Jan Olšan

Last week, AMD has unveiled the awaited expansion of the AMD Ryzen 7000 processor family with “X3D” models with 3D V-Cache. It boosts performance in games, so these could be very good (maybe even the best?) gaming PC processors. AMD has disclosed the specs, but hasn’t given the availability date for these models. We already have this information though, perhaps inadvertently, divulged by the company itself on its website. Read more “AMD Ryzen 7000X3D release date revealed? (Update: Sadly not)” »
