MrReynolds Posted February 1 Posted February 1 Hi all. I've built many a system myself - but now's the time to let someone else. As title really. Flying @4k (no VR YET). The system will have 64GB RAM and be paired with a 3080 until its MLU. They can both destroy AAA playstation games, I'm looking for recommendations for DCS. I'm not looking at Intel as I intend to upgrade the processor in a couple of years time and want to stay with the same socket and not bother with the motherboard shinanigans. Just take out and put in. I can't upgrade my current i7 to it's newer sibling for example. The company I'm looking at has the 7-9800x3d as £87 more than the 7-9800x3d. (GOD those numbers are confusing. Don't get me started on ZEN and AM sockets)! The 7800x3d is £42 cheaper, but I'm not thinking about that one. I've looked at benchmarks but open to suggestions. Any thoughts and recommendation MUCH appreciate. MrR.
Aapje Posted February 1 Posted February 1 (edited) You need to keep in mind that the AMD-chips with more than 8 cores have two compute-chiplets, with a high latency between them. Because of the high latency, you generally want to run the game on just one die. This is even more true when dealing with 3D-cache, which is only on one chiplet of the two. You then want to run the game only on the chiplet with X3D. The 9800X3D has one 8-core chiplet with X3D. The 7900X3D has a 6-core chiplet with X3D, plus another 6 core chiplet that is generally not much use in gaming. So from a gaming perspective, you can argue that it actually has fewer cores. Furthermore, the 9800X3D can boost higher due to them moving the X3D-cache below the compute, which means that it suffers less from the heat, and the CPU can thus clock higher. So my answer is the 9800X3D, if it's just for gaming. Edited February 1 by Aapje 2 1
Burning Bridges Posted April 1 Posted April 1 I researched this topic over the last year, and it's rather complicated. What I am quite sure is that the 9800X3D is a safest bet and will work great because it is only 1 chiplet. The 9900X3D could be better under certain ciurcumstances but you'd need a lot more research. Both are rather overpriced at the moment though, so I'll wait until the end of the year. 1
Aapje Posted April 2 Posted April 2 The 9800X3D is currently at MSRP, and availability seems good now. The question is when the price will start dropping significantly. The issue is that Intel is not very competitive, so we might not see prices drop that fast. 1
