Is DDR5 RAM worth paying more for over DDR4?

DDR5 is usually worth it for a new build, and not worth it as an upgrade to a DDR4 machine, because the two do not fit the same slots. The real question is which platform you are on.

Your situation	What to buy	Why
New PC on AMD AM5 (Ryzen 7000 series and later)	DDR5	AM5 supports DDR5 only
New PC on Intel LGA 1851	DDR5	LGA 1851 supports DDR5 only
New PC on Intel LGA 1700 (12th to 14th gen Core)	Either, set by the motherboard	LGA 1700 boards come in DDR4 or DDR5 versions
Adding RAM to an existing DDR4 PC	DDR4	DDR5 modules do not fit DDR4 slots

Sources: socket specifications for AMD AM5, Intel LGA 1700 and Intel LGA 1851; JEDEC DDR4 and DDR5 standard grades.

If you are on LGA 1700 and already own a good DDR4 kit, a DDR4 motherboard lets you reuse it and spend the savings elsewhere. If you are starting from scratch, DDR5 keeps you on the newer platforms, which is where both AMD and Intel have moved.

DDR5 RAM: how it differs from DDR4

DDR5 roughly doubles DDR4's top standard speed and raises bandwidth, while real latency stays about the same. Here are the headline numbers from the published standards:

Spec	DDR4	DDR5
Standard released	2014	July 2020 (JEDEC)
Standard speed grades	DDR4-1600 to DDR4-3200	DDR5-4000 to DDR5-8800
Bandwidth per module (top common grade)	25.6 GB/s at DDR4-3200	38.4 GB/s at DDR5-4800, 48 GB/s at DDR5-6000
Nominal voltage	1.2 V	1.1 V
Channels per module	One 64-bit channel	Two independent 32-bit subchannels
Power management	On the motherboard	On the module itself
Real latency	About 14 ns	About 14 ns

Sources: JEDEC standard grades and DDR4 and DDR5 specifications as summarised in the DDR4 SDRAM and DDR5 SDRAM reference pages.

What this means in practice: DDR5 moves more data per second, which helps tasks that stream lots of data such as video editing, 3D work and large file compression. In many games the gain is smaller than the speed numbers suggest, because the real latency is about the same and the graphics card often sets the pace. DDR5 also carries on-die error correction inside each chip, which is different from full ECC memory used in servers.

DDR5 RAM in 2026: why prices are higher

RAM costs more in 2026 because of a global memory supply shortage that began in 2025, as memory makers shift production toward chips for AI data centers. DRAM prices reportedly rose by about 172% over 2025, and that has carried through to retail prices for both DDR4 and DDR5 kits.

Micron's CEO said in June 2026 that he expected the shortage to last through 2027, with supply improving gradually by 2028. In August 2026, a Samsung executive said he expected it to continue through 2028, and SK Hynix's CEO said it could persist until 2030, according to reports compiled on Wikipedia's memory shortage page. There have also been reports that Intel plans more processors for its DDR4-capable LGA 1700 socket in 2027 because of DDR5 supply. Plans like that can change, so treat them as signs of a tight market rather than firm dates.

For you as a buyer, this means three things:

• Prices move often. A kit's price can change from week to week, so compare stores on the day you buy.
• Your old RAM has value. If your current PC is DDR4, an LGA 1700 board that takes DDR4 can save you buying new memory at all.
• Buy the size you need now. In a tight market, a right-sized kit beats paying for capacity you may not use.

DDR5 RAM best deals in the US for 2026

The best DDR5 deals in the US usually come from comparing the exact same kit across stores, buying around the big sale days and using a store's own deal programmes. Follow these four steps:

1. Step 1: compare prices. Search the same brand, capacity, speed and timing (for example, a 2 x 16 GB DDR5-6000 kit) at Newegg and Best Buy.
2. Step 2: look for a promo code. Check the store's own deals and its ShopBack page for a valid code. Our guide to finding promo codes that work explains which sources are safest.
3. Step 3: go through ShopBack. Open Newegg or Best Buy from ShopBack US and activate it before you check out.
4. Step 4: pay with your best rewards card. This is covered in its own section below.

Timing helps too. Black Friday is Friday 27 November 2026 and Cyber Monday is Monday 30 November 2026, and PC parts are a common sale category around those days. Our US sale calendar lists the other big windows.

Other electronics stores you can shop on ShopBack US include Adorama, HP and Walmart, alongside Newegg and Best Buy.

Newegg vs Best Buy: DDR5 RAM price comparison for 2026

Newegg and Best Buy both sell DDR5 kits online in the US; Newegg is built around PC parts and deal tools, while Best Buy pairs online shopping with store pickup and its membership programme. Compare them on these points:

What to compare	Newegg	Best Buy
DDR5 range	Wide; Newegg's filters list kits from DDR5-4800 to DDR5-8800 from brands such as Corsair, G.SKILL, Kingston, Crucial and TeamGroup	A curated range of popular desktop and laptop memory
Store deal programmes	Shell Shocker daily deals, Combo Deals, Newegg Outlet, Make an Offer on some items	My Best Buy membership, with free and paid tiers
Build help	PC Builder tool	In-store Geek Squad services
Getting it	Shipping	Shipping or store pickup

Newegg suits buyers who want the widest choice of speeds and timings and who like to bundle RAM with a CPU or motherboard through Combo Deals. Best Buy suits buyers who want to pick up today or prefer to shop with a membership they already use.

For a fair price comparison, match the kit exactly, including capacity, speed, CAS latency and whether it is one stick or two. Then compare the total with shipping and tax. Whichever store wins, go through ShopBack US before you pay. For more on Best Buy, read our guide on saving at Best Buy.

Newegg and Best Buy: buying DDR5 RAM in the US step by step

Buying the right DDR5 kit takes about fifteen minutes: confirm your platform, pick a size and speed, compare the same kit at both stores, then go through ShopBack and pay.

1. Confirm the memory type. Check your motherboard's manual or product page for DDR4 or DDR5 and the supported speeds.
2. Pick the capacity. A two-stick kit runs in dual-channel mode; 2 x 16 GB is a common choice for gaming and everyday use.
3. Pick the speed. Choose a speed on your board's supported list. Faster kits usually cost more.
4. Compare the same kit at Newegg and Best Buy, including shipping and tax.
5. Check for a code from the store or its ShopBack page.
6. Go through ShopBack. Open the store from ShopBack US, activate it and check out in the same session.
7. Keep the box and receipt until the PC boots and the memory runs at its rated speed, in case you need a return or exchange under the store's policy.

Paying with a rewards card when you buy RAM

After you go through ShopBack, paying with your best rewards card can usually lower the cost a little more, but check the merchant's terms and your card's terms first. Card rewards come from your card issuer, while ShopBack's cash comes from going through ShopBack, so the two usually apply to the same order. Some card offers exclude certain stores or payment types, so read both sets of terms. Our guide to using ShopBack with credit cards explains how this tends to work in the US.

How ShopBack US lowers what you pay for DDR5 RAM

Going through ShopBack gets you a cash rebate on the same order, at the same store. You still buy from Newegg or Best Buy at their price, and ShopBack sends part of what you spent back to you as cash.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.

Here is a worked example with an illustrative rate: on a $200 DDR5 kit at an illustrative 3%, $6 comes back, so the effective price is $194. Rates differ by store and by product category, and some items may be excluded, so check the live rate and terms on the Newegg or Best Buy page on ShopBack US before you buy. Our guide on activating before you buy walks through the steps.

Frequently asked questions

Is DDR5 RAM worth paying more for over DDR4?

For a new PC, usually yes, and on many new platforms you have no choice: AMD's AM5 socket and Intel's LGA 1851 socket support DDR5 only. DDR5 runs at standard speeds of 4,000 to 8,800 MT/s against DDR4's 1,600 to 3,200 MT/s. If you are adding memory to an existing DDR4 PC, buy DDR4, because DDR5 will not fit a DDR4 slot.

Can I put DDR5 RAM in a DDR4 motherboard?

No. DDR5 and DDR4 modules use different physical interfaces and the slots are keyed differently, so a DDR5 stick will not fit a DDR4 slot. Check your motherboard's memory type in its manual or on the maker's product page before you buy.

Is DDR5 faster than DDR4 in games?

DDR5 offers much more bandwidth, but the gain you see depends on the game, the processor and the graphics card. DDR5 also has about the same real latency as DDR4, at around 14 nanoseconds, so the jump is usually smaller in games than the speed numbers suggest. Tasks that move a lot of data, such as video editing, tend to benefit more.

Which processors need DDR5 RAM?

AMD processors on the AM5 socket, starting with the Ryzen 7000 series, support DDR5 only, and Intel processors on the LGA 1851 socket also support DDR5 only. Intel's LGA 1700 socket, used by 12th to 14th generation Core processors, supports DDR4 or DDR5 depending on the motherboard.

Why is RAM so expensive in 2026?

A global memory supply shortage that began in 2025 has pushed DRAM prices up, as memory makers shift production toward chips for AI data centers. Micron's CEO said in June 2026 that he expected the shortage to last through 2027. Prices move often, so compare stores on the day you buy.

How much RAM do I need for a new PC?

Many buyers choose a two-stick kit so the memory runs in dual-channel mode, which AM5 and LGA 1700 boards both use. A 2 x 16 GB kit is a common choice for gaming and everyday use, and heavier creative work often calls for more. Check what your main apps and games recommend before you pick a size.

What DDR5 speed should I buy?

Buy a speed your processor and motherboard support. Newegg lists DDR5 kits from DDR5-4800 up to DDR5-8800, and the fastest kits usually cost the most. Check your motherboard's supported memory list, then pick the speed and capacity that fit your budget.

Should I buy DDR5 RAM at Newegg or Best Buy?

Compare both for the exact same kit. Newegg carries a wide range of DDR5 kits and runs Shell Shocker daily deals, Combo Deals and a PC Builder tool, while Best Buy runs its My Best Buy membership and offers store pickup. Whichever is cheaper on the day, go through ShopBack US before you pay.

How does ShopBack lower the price of a RAM kit?

Going through ShopBack gets you a cash rebate on the same order, at the same store. Open Newegg or Best Buy from ShopBack US, buy your kit as usual, and part of what you spent comes back as cash. The live rate and terms, including any excluded items, are on each store's ShopBack page.

Is cashback the same as store reward points?

No. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles that you can only spend at one store.
