There are still a few years left before such a memory is released. HBM4 memory will appear on the market only in a few years, but it has already become known that its appearance may be associated with a small revolution in the field of semiconductor production. Hynix is ​​reportedly working with Nvidia and other manufacturers on technology that will allow HBM4 memory chips to be placed directly on the computing chip. [caption id="attachment_83411" align="aligncenter" width="600"] CPUs and GPUs[/caption] Now HBM memory is placed on the same substrate as the CPU or GPU, but next to it. Placing memory on the CPU/GPU will not only change the way logic and memory devices are typically connected, it will also change the way they are manufactured. This will change the way CPUs and GPUs are made. In fact, this is approximately the same as AMD's 3D V-Cache, only with a different type of memory. SK Hynix has now begun recruiting specialists to design logic semiconductors such as CPUs and GPUs and is discussing its HBM4 integration design method with several companies without its own manufacturing capabilities, including Nvidia. It is likely that Hynix and Nvidia will initially jointly develop a specific GPU, and then TSMC will produce this chip and immediately place HBM4 memory on top. Considering the type of memory, we are clearly talking about specialized accelerators for AI or data centers. [caption id="attachment_83412" align="aligncenter" width="385"] CPUs and GPUs[/caption] Hynix took on this idea for a reason. The thing is that HBM4 memory will use a 2048-bit interface to connect to host processors, so the latter will be extremely complex and expensive. A direct connection between memory and CPU/GPU will simply be cheaper. However, it is too early to draw any conclusions, since on the way to such implementation there is a very banal problem - heating. The consumption of the Nvidia H100 accelerator is very high, and in a few years such solutions can consume much more. Memory also consumes a lot, and when all this is placed next to each other, there are no problems with cooling. And when a “sandwich” is created, the heating increases significantly with a smaller area of ​​the final crystal. Perhaps Nvidia accelerators in a few years will initially be designed exclusively for liquid cooling.

This is the Emerald Rapids generation The first leak has appeared on the Internet regarding the new Emerald Rapids generation Intel Xeon Scalable processors, which will be presented on December 14 along with Meteor Lake . [caption id="attachment_79561" align="aligncenter" width="780"] Intel processor[/caption] The flagship Xeon Platinum 8592+ has been revealed, which will offer 64 cores, which does not yet look particularly impressive compared to AMD’s 96-core monsters. And relative to Sapphire Rapids, this is an increase of only 4 cores. All cores, by the way, will be large. Technically, these are Raptor Cove cores, like the current Raptor Lake. The new CPU will receive 320 MB of third-level cache. The total with the L2 cache is already 448 MB. This will be one of the main improvements over the current generation Xeon Scalable. [caption id="attachment_79562" align="aligncenter" width="760"] Intel processor[/caption] The peak power of this Intel processor can reach 922W. 64-core Xeon Platinum 8592+ appeared on the Internet The test sample had frequencies of 1.9-3.9 GHz, and all cores can simultaneously operate at 2.5 GHz. The production CPU is expected to operate at frequencies of 2.0-4.0 GHz. The power limits PL1 and PL2 are 350 and 420 W, respectively. The peak reaches 764 W, but the CPU can be configured so that the value reaches 922 W. [caption id="attachment_79563" align="aligncenter" width="483"] Intel processor[/caption] The test copy in the CPU-Z benchmark scored 610 and 25,741 points in single-threaded and multi-threaded modes, respectively, but the result is not very good, which is apparently due to the unavailability of the software.

And we will see Core Ultra 5/7 on December 14 Intel Meteor Lake processors will be presented this year but at the very end. According to recent data, not all at once. [caption id="attachment_64479" align="aligncenter" width="780"] new Core Ultra processors[/caption] The announcement of new CPUs is expected on December 14, but the Golden Pig Upgrade Pack insider says that not all models will be shown to us on this day. We are talking about the announcement of the Core Ultra 5 and Core Ultra 7 models. But Core Ultra 9 will be released in 2024, and it is not yet clear when exactly. Intel can't or won't announce all the new Core Ultra processors at the same time. Why such a division would occur is unclear. At the same time, if a conditional month passes between announcements, then this in itself is not scary, since the younger Meteor Lake will appear in laptops as early as 2024. But at the same time, Core Ultra 9 can linger much more. However, taking into account all the existing leaks, we know that Core Ultra 7 will still have the same six large and eight small cores as Core Ultra 9, so there probably won’t be much point in chasing older CPUs. Insider Golden Pig Upgrade Pack once shared performance leaks of Intel CPUs of different generations and published Intel slides describing the Meteor Lake CPU.

Just an engineering sample The first tests and characteristics of the 60-core Intel Xeon Platinum 8580 processor have appeared on the Internet. We are talking about an engineering sample (ES2) of a processor from the Emerald Rapids line, which will be presented on December 14, and will hit the market next year. [caption id="attachment_58593" align="aligncenter" width="780"] Xeon Platinum 8580[/caption] These processors will replace the current Sapphire Rapids, offering a new architecture (Raptor Cove), but maintaining the Intel 7 process technology. The latter is the reason why the maximum number of cores will remain unchanged. Xeon Platinum 8580 appeared on the Internet [caption id="attachment_58594" align="aligncenter" width="780"] Xeon Platinum 8580[/caption] Each of the 60 processor cores has 2 MB of L2 cache, so the CPU has 120 MB of L2 cache in total. The third-level cache memory reaches an impressive 420 MB. However, Intel's brainchild is very far from the AMD Epyc Genoa-X line with its 1152 MB cache. It’s not worth focusing on tests yet, since this is an engineering sample.

In single-threaded mode, the Core i9-14900KF beat everyone The Core i9-14900KF processor appeared in the PassMark benchmark database and immediately became the leader in the single-threaded performance rating. [caption id="attachment_58562" align="aligncenter" width="780"] Intel CPU[/caption] Despite the fact that technically the Core i9-14900K/KF is a complete copy of the Core i9-13900KS, apparently, there are some settings related to power limits. As a result, the new model is still a little faster than its predecessor, although this is unlikely to be noticeable in practice. The results of the new Intel CPU have appeared in PassMark But in multi-threaded mode, which is much more important from a practical point of view, everything is more interesting: the new product differs vanishingly little in performance from the Core i9-13900K and is even inferior to the Core i9-13900KS. And all of them are noticeably behind the Ryzen 9 7950X3D.

Initially, only K and KF models will appear The Videocardz resource reports that its sources have revealed the launch date of the new Intel Raptor Lake Refresh processors. The advertising embargo will be lifted on October 16, meaning on this day Intel partners will be able to disclose various details about their products related to the new CPUs. On October 17, at 16:00 Moscow time, the embargo on reviews will be lifted. Sales start on the same day. [caption id="attachment_54848" align="alignnone" width="780"] Intel processors[/caption] New and old Intel processors will be released on October 17, but not all It is worth noting that these dates only apply to the top-end Core i9-14900K, Core 7-14700K, and Core i5-14600K models, as well as their F versions with the iGPU disabled. That is, as almost always in recent years, the top models of the new generation will hit the market first, and everyone else will have to wait. However, let us remind you that in the Raptor Lake Refresh line, only Core i7 models will offer something conditionally new, which will have more cores than the 13th generation Core i7. In all other cases, we will only talk about increasing frequencies.

Frequency reaches 6GHz The Core i9-14900K processor lit up in the CPU-Z test, which confirms its characteristics, and at the same time allows you to compare the new product with its predecessor. [caption id="attachment_51251" align="aligncenter" width="780"] new Intel CPU[/caption] The new CPU will indeed be an almost complete copy of the Core i9-13900K. The same 24 cores, the same amount of cache memory, but the frequency will increase to 6 GHz, that is, by 200 MHz.  Not 3%, but as much as 8-10% of the increase in the new Intel CPU. In the benchmark, the CPU scores 978 and 18,118 points in single-threaded and multi-threaded modes, respectively. Thus, the new product is 8-10% faster than its predecessor. This is not bad, considering the almost identical parameters, but you need to understand that in real applications the gain may be less. But relative to the Core i9-12900K, the increase reaches a much more impressive 19% and 59%, depending on the mode. Let us remind you that the Raptor Lake Refresh line is expected in October.   [caption id="attachment_51254" align="aligncenter" width="780"] new Intel CPU[/caption]
