Intel’s 1st Gen Core Ultra Meteor Lake CPUs Encounter Sluggish Memory Speeds: A Comparative Analysis with 13th Gen Raptor Lake.

Intel’s 1st Gen Core Ultra Meteor Lake CPUs Encounter Sluggish Memory Speeds: A Comparative Analysis with 13th Gen Raptor Lake

Intel has been stirring up the tech industry with its upcoming Meteor Lake processors. These chiplet-based CPUs from Team Blue are set to revolutionize the market with their heterogeneous core mixture and varying process technology. However, a recent leak suggests that the Core Ultra chips may face a significant hurdle in the form of slow memory speeds.

According to the leak, the Intel Core Ultra 9 185H, when subjected to the AIDA64 cache/memory benchmark, recorded an L3 cache Latency of 49 ms. This is nearly three times higher (or worse) than the 13th Gen Raptor Lake processors. The L3 read, write, and copy speeds also fell short, dropping to 568/s, 303GB/s, and 372GB/s, respectively. In comparison, the Core i9-13900K reported significantly higher values of 1821GB/s, 636GB/s, and 1,000GB/s for read, write, and copy speeds, with a latency of 16.9ms.

The situation doesn’t improve when we look at the L1 and L2 bandwidth. The 185H chip reported L1 read and write speeds of 1471GB/s and 1479GB/s, while the 13900K achieved 5811GB/s and 3554GB/s, respectively. This means that the Core Ultra chip is four times slower than its 13th Gen counterpart in terms of L1 bandwidth. However, the latency figures for L1 and L2 were relatively closer, coming in at 1.0ns and 0.9ns for the two chips, respectively.

It is worth mentioning that these values might represent the memory bandwidth/latency of the LP cores on the SoC die, as they lack an L3 cache altogether. AIDA64 has recently released a beta patch to address the reported figures on hybrid core processors, but it remains uncertain if these changes will have a significant impact.

While these findings raise concerns about the memory performance of Intel’s 1st Gen Core Ultra Meteor Lake CPUs, it is essential to remember that this is based on leaked information. To draw a definitive conclusion, we must wait for the official launch and subsequent third-party benchmarks.

It is also important to note that unlike AMD’s chiplet CPUs, all of Intel’s P and E cores are located on the same die. This reduces the chances of encountering memory speed penalties, unless we consider the LP cores on the SoC die.

In conclusion, Intel’s 1st Gen Core Ultra Meteor Lake CPUs may face challenges with sluggish memory speeds, as indicated by leaked benchmark results. However, it is too early to make a final judgment without official confirmation and comprehensive third-party testing. As technology enthusiasts eagerly await the official launch, it remains to be seen how Intel will address these potential issues and whether they will impact the overall performance of their highly anticipated processors.

Latency: Technology latency is the time it takes for a computer system to respond to a request. It is an important factor in the performance of computer systems, as it affects the speed and efficiency of data processing. In the computer industry, latency is a major factor in the performance of computer networks, storage systems, and other computer systems. Low latency is essential for applications that require fast response times, such as online gaming, streaming media, and real-time data processing. High latency can cause delays in data processing, resulting in slow response times and poor performance. To reduce latency, computer systems use various techniques such as caching, load balancing, and parallel processing. By reducing latency, computer systems can provide faster response times and improved performance.
