Core i7-14700K vs. Core i7-13700K: Five percent more single-core performance, with 30 watts more consumption (report)

Core i7-14700K vs. Core i7-13700K: Five percent more single-core performance, with 30 watts more consumption (report)

On the video-sharing website Bilibili, which is particularly popular in China, an Intel Core i7-14700K from the upcoming “Raptor Lake Refresh” competed for the first time against its direct predecessor, an Intel Core i7-13700K, and was doing so with regard to its single -Measure core performance and multi-thread performance as well as its consumption and compare them accordingly. As expected, the results have turned out to be rather sobering. In the end, more clock frequency means a little more performance with higher consumption.

A little more power = higher consumption

The Chinese reviewer “T小白” has now published the first test results of an Intel Core i7-14700K on his channel on Bilibili, which had to compete against an Intel Core i7-13700K. The “Raptor Lake Refresh”, which according to the current information is expected to celebrate its premiere in October with the K models on the desktop, competed against its predecessors in CS:GO, Genshin Impact and PUBG as well as Cinebench R23 and CPU-Z. The high power consumption negates the theoretical gain.

In CPU-Z and Cinebench R23, single-core performance is up an average of 4 to 4.5 percent, while multi-threaded performance can unsurprisingly increase by 14 to 20 percent now that the new i7-14700K is overall has four additional efficiency cores. Basically, nothing has changed in terms of performance per processor core.

Probably not much faster in games

The Intel Core i7-14700K, which is still read as “Core i7-13700KS” in the Chinese reviewer’s test, is only slightly faster than its direct predecessor in the tested games. The 1 percent percentile fps, which is so important for a smooth gaming experience, only increase in the low single-digit percentage range. Games aren’t likely to be that big of a beneficiary of the Raptor Lake-S refresh.

The additional consumption in games should be kept within limits due to the comparatively low loads. It looks different when the total of 16 processor cores (8P + 16E) and 24 threads are loaded.

30 watts more consumption in the multi-thread benchmark

In the multi-thread benchmark of the well-known system suite AIDA64, the Intel Core i7-14700K consumes significantly more power than the Core i7-13700K. Instead of the previously measured around 231 watts (i7-13700K), around 261 watts (i7-14700K) are available after a CPU change. An increase of around 13 percent, which should also have consequences for the heat development and cooling of the hybrid CPU.

The average maximum clock (“boost”) in the AIDA64 multi-thread benchmark is exactly 5.5 GHz on the P cores and 4.3 GHz on the E cores. Thus, the Core i7-14700K clocks an average of 100 to 200 MHz higher than its predecessor.

Specifications are almost guaranteed

Due to various, usually reliable sources from Asia, but also numerous entries from various benchmark databases, the specifications that have been leaked so far are now more than just a rumor. Nevertheless, in the end nothing is set in stone and a limited KS model cannot be ruled out, but currently unlikely.

Here are all the Core i 14000 series leaked specs so far compared to its two predecessors, Core i 13000 and Core i 12000, based on multiple different and independent sources.

*) not officially confirmed yet!

There will probably not be an increase in the number of cores in the new Intel Core i5 and Core i3, as the rumor mill had briefly speculated beforehand. Only the Intel Core i7-14700K and later modifications of this model get a total of four additional small efficiency cores. Will that be enough?

The benchmarks previously published by Igor’s Lab also saw the refresh only marginally ahead of the original, and the small product update of the Raptor Lake-S will certainly not make a big leap forward. The maximum clock speed of 200 MHz will probably go to waste for the most part, even if only independent benchmarks with the final product will allow a final assessment. In all likelihood, it won’t be long before certainty prevails.

K models in October and the rest will follow in 2024

As various OEM partners from the Chinese trade have meanwhile confirmed, the Raptor Lake refresh in the form of the K models is to be launched in October. The regular models without a suffix, on the other hand, should not appear until the beginning of next year. The presentation of the Core i 14000 series is expected to take place on September 19 at Intel Innovation.
