PS5 and Xbox RAM: Specs and Can You Upgrade It?

How much RAM does a PS5 have?

The PS5 has 16GB of GDDR6 memory on a 256-bit interface with 448 GB/s of bandwidth. The processor and the graphics share that one pool. That holds for the standard PS5 and the Digital Edition.

Sony does not print the memory on its own PS5 product pages. The figures come from Digital Foundry's coverage of the console in March 2020, as summarized on Wikipedia, and they have been repeated widely since. Next to the main memory, the PS5 is also reported to have a small DDR4 cache that serves the SSD controller. You never see or manage that part.

The PS5 Pro is reported to keep 16GB of GDDR6 for games and add 2GB of DDR5 for the system software. That comes from leaks before launch and a teardown report, not from Sony. Sony's PS5 Pro page lists the 2TB SSD but says nothing about memory, so treat the 2GB as reported, not confirmed.

If you are new to the basics of memory, our guide on what RAM is explains how it differs from storage.

Xbox Series X and Series S memory

Microsoft does publish its numbers. The Xbox Series X has 16GB of GDDR6 on a 320-bit bus. The memory is split in two speeds: 10GB runs at 560 GB/s and 6GB at 336 GB/s.

The Xbox Series S has 10GB of GDDR6 on a 128-bit bus. Here 8GB runs at 224 GB/s and 2GB at 56 GB/s. So the Series S has 6GB less memory than the Series X, and its fastest part runs at well under half the speed.

PS5 and Xbox memory side by side

The table below puts the four current consoles next to each other. The PS5 rows are reported figures; the Xbox rows come from Microsoft's spec pages.

On paper the PS5 and the Series X have the same 16GB. The difference is in how the memory is wired and how fast each part of it runs, not in the amount.

Can you upgrade PS5 or Xbox RAM?

No. Neither console has a way to add memory. Microsoft's spec pages list no RAM upgrade path for the Series X or Series S, and the PS5 has no memory slot for users either. What you get on day one is what the console keeps for its whole life.

What you can upgrade is storage. The PS5 has an internal M.2 slot for an NVMe PCIe Gen4 x4 SSD, and since the update of September 13, 2023 it takes drives up to 8TB. The Xbox Series X and Series S take Storage Expansion Cards made for those consoles, with a 1TB card listed on Microsoft's page. More storage means more games installed at once. It does not make games run faster and it does not add RAM.

Why console memory is not the same as PC RAM

The PS5 uses one pool of GDDR6 that the processor and the graphics share. A desktop PC uses DDR4 or DDR5 modules that click into slots on the motherboard, and a DDR5 module only fits a DDR5 board. The bandwidth numbers show how different the two are. Kingston gives DDR5-6400 a peak of 102.4 GB/s in dual channel, against 448 GB/s for the PS5's shared GDDR6.

So 16GB in a console and 16GB of DDR5 in a PC are not the same kind of memory, and a PC kit tells you nothing about how a console performs. If you game on both, our page on how much RAM you need covers what a PC needs, and the gaming RAM guide shows which kits make sense.

Apple silicon Macs have the same limit: the memory sits in the chip package, you choose it when you buy, and it cannot be upgraded later. Our Mac RAM guide explains that case.

What the memory shortage means for consoles

Consoles do not escape the memory crunch. The Guardian reported that Sony raised the UK price of the PS5 by GBP 90 on April 2, 2026, during the same wave of price increases that hit laptops and phones. We did not find a verified US figure for that change.

The memory inside the PS5 and the Xbox is GDDR6. In its September 30, 2026 outlook, TrendForce said suppliers are scaling back GDDR6 and gradually exiting it, while the large makers keep cutting consumer DRAM production. TrendForce expects consumer DRAM prices to keep climbing, at a slower pace.

Forecasts for the next year differ. TrendForce expects conventional DRAM contract prices to go up 10% to 15% in the fourth quarter of 2026. A June 2026 forecast from the bank Jefferies, reported by PC Games Hardware, was higher: 30% to 40% for the same quarter and the first relief no earlier than 2028. Our RAM price forecast follows these views as they change.

For PC builders the effect shows up in kit prices. This week the cheapest 16GB DDR5 desktop kit in our US data costs $237.00 and the cheapest 32GB kit $449.99, excluding sales tax. Change over the last 4 weeks in the median price per GB of 32GB DDR5 desktop kits: not measured yet. You can compare every kit on our RAM prices page.

What we do not know yet

• Official PS5 memory specs. Sony's own pages do not list the memory of the PS5 or the PS5 Pro. The figures on this page are widely reported, and the PS5 Pro's extra 2GB of DDR5 comes from leaks and a teardown.
• US console prices. We have no verified source for a US PS5 price change linked to memory costs, so we do not quote one.
• Whether GDDR6 cuts reach consoles. TrendForce says suppliers are scaling back GDDR6. Whether that changes console production or prices has not been reported by Sony or Microsoft.
• The next console generation. Neither company has published memory specs for a successor. Anything you read about it today is a rumor.

We track RAM kit prices in US shops every week, last on November 2, 2026. Console memory is not part of that data, because you cannot buy it separately.
