AMD's re-released Ryzen 7 5800X3D sold out almost immediately when it launched, and since then, we've seen scalpers circle the chip and demand double the MSRP (or more). Hopefully, we'll get more in stock, but if you're tired of waiting, you can easily upgrade to a DDR5 platform with these Prime Day CPUs deals, all of which are cheaper than the 5800X3D's recommended $350 MSRP.
The idea is that if you can save money on your CPU, you'll have more money to spend on DDR5. And although the total platform cost rises above that $350 mark, you also make out with a much better processor, as well as DDR5 memory that you can use for future upgrades.
Based on our daily RAM price tracking, you can expect to spend around $150 to $200 on a 16GB kit of DDR5 memory right now, while 32GB kits sit around $400. We recommend 32GB for most systems, but 16GB will get you by in the meantime. With some of these CPUs, the discount completely eliminates the cost of buying DDR5, in fact.
The Ryzen 7 5800X3D is currently in stock on Amazon for MSRP. However, it's on back order, with estimated ship times in the second half of July. Given that time frame, that's when we expect a larger restock of the chip across retailers.
This sale on the Ryzen 7 7700X completely eliminates the cost of 16GB of DDR5 memory. The Ryzen 7 5800X3D is $350, the Ryzen 7 7700X is only $200 right now, so you can make out with a newer eight-core CPU on AMD's Zen 4 architecture and 16GB of DDR5 for around the same price. You might spend around $50 more depending on the RAM kit you find, but you'll also make out with a more powerful CPU.

The Ryzen 7 7700X may not sport AMD's 3D V-Cache, but it roundly beats the 5800X3D in games and applications. As you can read in our recent re-review of the Ryzen 7 5800X3D, it's clear the CPU maxes out DDR4's gaming potential, and pushing beyond the performance it offers requires a swap to DDR5.
You'll need an AM5 motherboard for the Ryzen 7 7700X, along with DDR5 memory. Unlike Intel, you can overclock AMD's chips on B-series chipsets, saving you some additional money compared to the competition.
If you want a great all-around CPU, you can't miss this deal on the Intel Core Ultra7 270K Plus. The CPU has an MSRP of $300, but we've seen it sold exclusively for $350 since it was released earlier this year. It's on a true sale for the first time this Prime Day, and a deep one at that, bringing the price down to $265.

Intel's latest Arrow Lake Refresh CPU handily beats the Ryzen 7 5800X3D. In games, you get a solid 13.7% jump in average performance, and in multithreaded applications, the 270K Plus is more than twice as fast. The 270K Plus is only beaten by AMD's crop of Ryzen 9 9950X variations, in fact, so you can get flagship productivity performance for just $265. That's incredible.
Although Arrow Lake has caught a lot of flack for its poor performance, the 270K Plus from Arrow Lake Refresh is genuinely impressive at list price, and even more so on a deep discount.
Finally, we have the successor to the 5800X3D, AMD's Ryzen 7 7800X3D. Hilariously, it's cheaper than the 5800X3D right now by $2. And, as you can see in our benchmarks above, it's much faster in both games and applications.
Of course, the actual price is higher as you need to buy a kit of DDR5 memory to pair with the 7800X3D. This deep of a discount eases that burden, though. We've seen the 7800X3D as low as $320, but only on limited-time lightning sales. It's still a great deal at $348.
These are the CPUs we recommend if you finally want to upgrade to DDR5, especially with their Prime Day discounts. However, you can shop all the CPU deals on Amazon if you want more options.
