DDR4 can support those speeds but check compatibility with your motherboard and other components.
DDR4 can support those speeds but check compatibility with your motherboard and other components.
It's clear you're pointing out the right path. For 14700k/14900k, go with DDR5 instead of DDR4—it's meant for higher-end builds. The 14900k is way beyond budget options, so using D5 will give you a big performance boost. Just make sure your components are set up correctly for the best results.
I understand the video you're mentioning, but the testing methods used aren't very reliable. The "first word latency" doesn't really matter much for memory performance, and it's not a fair comparison between DDR4 and DDR5. Video editing demands more memory bandwidth than simple latency issues, which is why DDR5 excels in that area. This doesn't mean DDR4 would be terrible, but DDR5 would be significantly faster. If you can upgrade, I'd recommend doing so.
For a fresh installation or complete overhaul where you're purchasing a new CPU and motherboard, I prefer a DDR5 setup. Personally, I stick with DDR4 now because when the Z690 chipset launched and my board was released, DDR5 was prohibitively expensive compared to DDR4. Going DDR4 isn't significantly more affordable in that scenario. I currently run a 14900K with 64GB of 3600MHz DDR4 without any issues. Before that, I used 32GB and it worked just fine as well. If your system has a solid 3200MHz or higher, you should be okay. For tasks like video rendering and editing, I suggest moving from 16GB to at least 32GB depending on the software. DDR4 remains very affordable today, making upgrading to 32GB a straightforward decision.
@KazerLight3 DDR4 consistently outperforms DDR5 in initial word latency, though this isn't the whole story. DDR5 offers significantly higher bandwidth, which benefits tasks like video editing. Consequently, DDR4 edges slightly in games such as CSGO (though I don’t know about CS2), while DDR5 excels in scenarios demanding more data throughput. If you opt for a 14900K, choosing DDR5 makes sense, but if budget matters, sticking with DDR4 is still viable. Generally, when your system is GPU-intensive or runs CPU-heavy apps, the price difference between the two isn’t worth it.
The 13th generation memory system differs significantly from the 12th generation one. During Puget's evaluation, Premier showed strong scaling with memory frequency, indicating a high bandwidth demand. https://www.pugetsystems.com/labs/articl...23-update/ Additionally, GN's testing uses manually adjusted DDR4, whereas XMP settings are applied for DDR5. This makes the comparison less straightforward.
It's refreshing to notice Intel isn't just reselling the same models on the 13th and 14th. Comparing DDR4 and DDR5 is much more common now, and it's frustrating when Pudget doesn't recheck DDR4 at the same time. If you're purchasing new components, switching back to DDR4 doesn't really add value unless you're replacing an older system. Upgrading an existing rig likely isn't worth it for that reason.
Paid for memory is beneficial. I support reusing components. Keep in mind CL is expressed in cycles. DDR4-3600 provides only 60% of the cycles compared to DDR5-6000. The gap in latency between these two will remain relatively consistent because 16 is close to 60% of 30. Be aware that cache typically buffers most memory requests. Cache sizes have grown significantly, making misses much less common. Consequently, more often when data isn't cached it involves reading large amounts sequentially, and in those scenarios bandwidth becomes the main bottleneck. Previously, memory accesses were more like a mix of many small random reads and occasional long reads, where latency had a bigger impact.
