At CES this year AMD announced three upcoming additions to their 7000 Series of CPUs which all featured 3D V-Cache like the popular Ryzen 7 5800X3D. Then late in February, the first two models were released but the third and lowest-priced model of the three, the Ryzen 7 7800X3D wasn’t included. Well, today the embargo lifts on the new 7800X3D and we can finally dive into its performance ahead of it being available in stores tomorrow. So why waste any time, let's quickly go over what sets it apart and then get into its performance.

What is the Ryzen 7 7800X3D

In our coverage of the 7950X3D, I dove into it and the 7900X3D’s unique design which has an asymmetric chiplet layout that combines a traditional CCX alongside of one paired up with AMDs 3D V-Cache. This was AMDs way of utilizing the 3D V-Cache while keeping the cost down when it comes to the 12 and 16-core models that would need twice as much 3D V-Cache. This also allowed them to still utilize the higher frequency standard cache as well. All of that required a specific driver to optimize everything to make sure you were running the optimal configuration at all times. The 7800X3D doesn’t have that configuration, like the 5800X3D before it, the Ryzen 7 7800X3D has just one CCD and doesn’t have to worry about the special optimization because it only has the 3D V-Cache paired up with its 8 cores.

So the core count has dropped down when compared to the 7900X3D and the 7950X3D and this helps better show the focus of each of these CPUs. The 7950X3D  and the 7900X3D can game but can also handle content creation. The 7800X3D that we have here today on the other hand is designed with just gaming in mind. The product naming does get interesting though because the 7900X3D and the 7950X3D both had matching non-3D models but there isn’t a 7800X, at least from the Ryzen lineup Intel did have one back in 2017. It actually matches up with the 7700X which has the same 8-core and 16-thread layout. Like with the other 3D models when compared to their counterparts the 7800X3D does have a lower max boost and base boost compared to the 7700X. It still reaches 5 GHz but isn’t up there like the others. The TDP has increased up to 120 watts and the max socket power reflects that increase as well as the EDC and TDC amps as well. Then like the other 3D V-Cache CPUs the TjMax is lower at 89c. The big change however is the l3 Cache which the 7700X has 32MB and the 7800X3D has a crazy 96MB.

The 7800X3D has a significantly lower MSRP than the 7950X3D which is $699 and the 7900X3D is $599. It has an MSRP of $449 which is $50 higher than the 7700X. The 7900 fits in a weird spot with its lowered price being $30 less as well but anyone gaming is still going to be looking at the 7800X3D, especially with it being the lowest-priced model with 3D V-Cache.

Like with the other 3D V-Cache CPUs, the 7800X3D is limited in its overclocking capabilities. You can turn on the curve optimizer and precision boost overdrive but you don’t have access to manual overclocks. Memory is fine though with Expo, XMP, or custom setting changes available.

AMD did send out our sample in the retail packaging which I always dig. Especially with the orange trim on the box and they did highlight the 3D V-Cache with the silver arrow having it mentioned and pointing right to the CPU window in the center that lets you see the actual CPU. Like the other 3D models, the 7800X3D doesn’t come with a cooler so the larger box is filled mostly with foam to fill that space. Inside you get a small piece of paper with installation instructions and the warranty information and another small piece of paper with a QR code to join the AMD Red Team. The CPU comes in their standard clear plastic clamshell as well which keeps it safe but lets it be seen through the window.

If you haven’t seen any of the new AMD AM5 CPUs there will be a few big surprises here. For starters, the clunky heat spreader of past Ryzen CPUs isn’t there. They have replaced that with the unique design that they originally showed on the 5800X3D announcement but wasn’t featured on the actual 5800X3D. Below that, though you will see that the CPU doesn’t have any pins, it now has an LGA-style socket like Intel has run for years. This does mean that the CPU is a little less likely to be damaged which is nice but that risk has been transferred to the motherboard socket, so be careful there. As always AMD has the heat spreader etched with the AMD Ryzen branding which looks great and the model name is just below that before getting the serial and build and revision info below that.
