Short answer: upgrading from AM4 to AM5 is worth it in 2026 if you are building from scratch, or if you would have to buy memory as well as a motherboard. If your PC has a 400- or 500-series AM4 board, drop a Ryzen 5000 processor into it and keep your DDR4: a Ryzen 7 5700X for general use, or a Ryzen 7 5800X3D if the PC is mainly for games. Check the board maker's CPU support list before you order. AMD has committed to the AM5 socket through 2029, but AM5 only takes DDR5, and DDR5 is where the money goes.
For most Ryzen owners, AM4 vs AM5 comes down to how many boxes you have to buy. A processor is one. AM5 is three, because the board and the memory change with it. The question keeps coming up on South African PC forums, so this guide gives rand totals for each route from AZ Online's own listings, the BIOS check to do before you order, and the point where we'd stop spending on AM4. If your PC predates AM4, you are probably looking at one of our CPU, motherboard and RAM upgrade kits.
AZ Online sells the parts named in this guide. Prices and stock change daily, so the prices sit in one dated table and every part in it links to its live page.
AM4 or AM5: which upgrade path fits your PC?
Your motherboard decides which upgrade path fits, and the processor already in it decides whether a swap is worth making.
| Your PC today | What we'd do | The catch |
|---|---|---|
| AM4, 400- or 500-series board (B450, X470, A520, B550, X570), processor older than Ryzen 5000 | Drop in a Ryzen 5000 processor. Keep the board and the DDR4. | It usually needs a BIOS update first, and the board's CPU support list has the final say. |
| AM4, already on a Ryzen 5000 processor | Probably nothing. Look at the graphics card first, unless you need eight cores for work or want the 5800X3D for games. | Every chip you could drop in comes from the family you already own. |
| AM4, 300-series board (A320, B350, X370) | Read the board maker's support list before buying anything. | AMD lists these boards as needing a selective beta BIOS for Ryzen 5000. If yours isn't covered, add a B550 board and keep your memory. |
| Older PC with 16GB or more of DDR4 | Keep the memory. Buy a processor and a B550 board. | The 5700X comes without a cooler, so check that your old one fits AM4. |
| Older PC with DDR3, or too little DDR4 | An AM4 upgrade kit, or AM5 parts if the budget stretches. | Board, processor and memory all change. |
| No PC yet | Build on AM5. | DDR5 pushes the starting cost up. If you need 32GB on a fixed budget, look at the AM4 32GB row in the cost table first. |
If you don't know which board you have, the model name is printed on it, usually between the expansion slots, and Windows shows it as BaseBoard Product in the System Information app.
What does each path cost in rand?
A drop-in Ryzen 7 5700X costs about a third of what a basic AM5 platform does at our prices, because AM5 means a board and DDR5 as well as a processor.
| Path | Parts to buy | What you reuse | Total (ZAR) |
|---|---|---|---|
| AM4 drop-in | AMD Ryzen 7 5700X | Board and DDR4 | R4 379 |
| AM4 drop-in for games | AMD Ryzen 7 5800X3D | Board and DDR4 | R8 299 |
| AM4 with a new board | Ryzen 7 5700X and MSI PRO B550M-A PRO | DDR4 | R6 228 |
| AM4 upgrade kit, 16GB | Ryzen 5 5600X LEVEL UP Core Upgrade Kit: Ryzen 5 5600X, MSI A520M board, 16GB (2×8GB) DDR4-3600, Wraith Stealth cooler | Nothing | R7 499 |
| New AM4 platform, 32GB | Ryzen 7 5700X, MSI PRO B550M-A PRO and two Hiksemi Hiker 16GB DDR4-3200 modules | Nothing | R10 286 |
| AM5 platform, 16GB | AMD Ryzen 5 7600, Gigabyte B840M D2H and two Hiksemi Hiker 8GB DDR5-4800 modules | Nothing | R12 464 |
| AM5 platform, 32GB | Ryzen 5 7600, Gigabyte B840M D2H and two Hiksemi Hiker 16GB DDR5-4800 modules | Nothing | R15 398 |
The two 32GB rows use Hiksemi modules that are on promotion until 18 December 2026, so expect both totals to rise after that. Coolers differ too: the Ryzen 5 7600 and the upgrade kit come with AMD's Wraith Stealth, while the 5700X and 5800X3D come bare.
Compare the two 32GB rows and AM5 costs about R5 000 more. Nearly all of that is memory. The Ryzen 5 7600 and the 5700X cost about the same and the AM5 board is a few hundred rand dearer, but none of your DDR4 carries over, and the DDR5 costs roughly double. The processors are not twins, though: the 5700X has eight cores and the 7600 has six.
That is why a new AM4 build is still defensible. The 32GB AM4 row comes in below the 16GB AM5 row. If the budget is fixed and you need 32GB now, AM4 does it for less, on the understanding that AMD has promised no further AM4 processors. If you can find the difference, we'd still start on AM5.
Two single modules are not a matched kit, so don't count on the pair running at the speed on the label. Our listing for the Gigabyte B840M D2H also shows no Wi-Fi and two memory slots, so going from 16GB to 32GB later means replacing both modules. If you expect to want 32GB, buy it up front.
The six-core Ryzen 5 5600 is a cheaper drop-in than the 5700X, and the same board rules apply to it.
Will a Ryzen 5000 chip work in my motherboard?
A Ryzen 5000 processor is a supported upgrade on 400- and 500-series AM4 boards, usually after a BIOS update. AMD's AM4 compatibility table ticks X570, B550, A520, X470 and B450 for Ryzen 5000 and marks X370, B350 and A320 as needing a selective beta BIOS. Its footnote adds that not every processor works on every board, and sends you to the motherboard maker's site to confirm.
Do the check in this order:
- Get the exact board model, including suffixes such as MAX or II, plus the revision number if one is printed on the board. Support lists are written per model.
- Open the board maker's CPU support list for that model and find the processor you want. ASUS's list for its TUF Gaming B550M-Plus WiFi II, for example, includes the 5800X3D.
- Note the BIOS version the list asks for and compare it with what your board is running. For the 5800X3D, Tom's Hardware's review of 29 May 2022 put the minimum at AGESA 1.2.0.6b.
- Update the BIOS while the old processor is still installed. Then swap chips.
Step four matters most. A board on firmware that predates the new chip may not start with it. Then you either refit the old processor to run the update or, on boards that have the feature, flash from a USB stick with no processor installed. The manual will say which.
We can't promise that a particular board will take a particular chip. The support list is the authority. If your board isn't on it, a B550 board keeps the rest of the plan intact, because your DDR4 moves across.
Is the Ryzen 7 5800X3D still worth buying in 2026?
The Ryzen 7 5800X3D is still worth buying in 2026 as a drop-in for a gaming PC that already has an AM4 board and DDR4, and not for almost anyone who has to buy those as well. That is also the verdict of Tom's Hardware's re-review of 25 June 2026: still a strong gaming chip for DDR4 systems, behind its DDR4 rivals in application work, and hard to justify once a board or memory is added to the bill.
The cost table shows why. Add the B550 board and 32GB of DDR4 to a 5800X3D and you land within about R1 200 of the AM5 32GB row. If you would be buying a board and memory anyway, look at AM5 and its own X3D processors instead. On our shelf they sit in the same price range as the 5800X3D.
AMD lists eight cores, 96MB of L3 cache and a 105W TDP for the 5800X3D, where the 5700X has the same core count with 32MB of cache at 65W. Tom's Hardware's 2022 review found the extra cache pays in games, measured the chip behind the ordinary Ryzen 7 5800X in some single-threaded work, and noted that its cores cannot be overclocked. If the PC earns its keep rendering or compiling, the 5700X gives you the same eight cores for a little over half the price.
Budget for cooling: AMD's page recommends a liquid cooler and there is none in the box. And if the graphics card is what holds your frame rate back, the money belongs there first.
In June 2026 AMD re-released the chip as a 10th Anniversary Edition. Tom's Hardware reports that AMD describes it as the same processor apart from a slightly different bonding process. Don't read that as a sign of more to come. Buy the 5800X3D as the last stop for your board.
Why is AM5 the better base for a new build?
AM5 is the better base for a new build because it is the socket AMD is still releasing processors for. On 31 May 2026 AMD extended its AM5 commitment through 2029. Tom's Hardware noted on 1 June 2026 that the previous promise, made in 2024, was 2027 and beyond, and that the new date carries no plus sign.
AMD has not said which processors the commitment covers. Its announcement names no future chip, and AMD told Tom's Hardware it could not comment on its roadmap. Igor'sLAB, writing on 9 July 2026, treats the next Ryzen generation as settled for AM5. That is a report, not an announcement, so don't price it into your decision as fact.
What the commitment buys, if AMD honours it the way it did on AM4, is a second processor for the same board and memory a few years on.
The people who shouldn't move are those with a working 400- or 500-series board and 16GB or more of DDR4. For them AM5 means paying again for two parts that aren't broken.
What about a DDR4 build on Intel?
Intel's LGA 1700 platform is the other way to build on DDR4. Tom's Hardware reported on 13 June 2026 that Intel plans one more processor refresh for the socket in the first half of 2027, and Intel declined to comment. The same outlet reported on 3 September 2026, citing leaks, that Intel's next desktop generation moves to a new socket.
If you are already on AM4, ignore it. You would be replacing a working board to land on another DDR4 platform with a short runway.
What if my PC is older than AM4?
If your PC is older than AM4, look at its memory before anything else. A PC with DDR4, which covers most Intel desktops from the 6th to the 10th generation, can keep that memory on an AM4 board, so a processor and a B550 board may be all it needs. That is the third row of the cost table.
When the memory is DDR3, or there is too little of it, the board, processor and memory all change together and an upgrade kit is the tidiest way to do it. The Ryzen 5 5600X LEVEL UP kit in the table carries a two-year warranty according to its listing. It needs a graphics card, because the 5600X has no integrated graphics, and the listing says the A520M board will not overclock.
The kit costs about R5 000 less than the 16GB AM5 row. The collection also has kits that cost less, including one with integrated graphics for a PC that has no graphics card. Either way the case, power supply and drives carry over, so be honest about their age before deciding a kit is all the PC needs.
Questions people ask
Is upgrading from AM4 to AM5 worth it?
Upgrading from AM4 to AM5 is worth it only if you would be buying memory as well as a board, or you want more than AM4 can give and have the budget for DDR5. A dead or unsupported board alone is not a reason. In our cost table a Ryzen 7 5700X with a new B550 board costs about half of what the 16GB AM5 platform does, and it keeps your DDR4.
What motherboard do I need for a Ryzen 7 5800X3D?
A Ryzen 7 5800X3D needs an AM4 board with a BIOS recent enough to recognise it. AMD's spec page lists five chipsets (X570, X470, B550, B450 and A520), and on a 300-series board support depends on the maker's BIOS updates, so confirm your exact model on the maker's CPU support list. If you would be buying a board and memory just to run one, build on AM5 instead.
Which AM4 CPU should I pair with an RTX 5070?
For an RTX 5070 on AM4, the 5800X3D is as fast as DDR4 platforms get in games, according to Tom's Hardware's June 2026 re-review, and the 5700X is the cheaper match. How much of the difference you see depends on the game and the resolution.
Do I need a new cooler for AM5?
Often you can reuse an AM4 cooler on AM5, but not in every case. PC Gamer reported on 6 January 2022 that AM5 keeps AM4 cooler compatibility, with exceptions. Check the cooler maker's socket list before you reuse one.
Will my DDR4 RAM work on an AM5 board?
No, DDR4 memory does not work on an AM5 board. AMD's spec pages list DDR5 as the memory type for AM5 processors such as the Ryzen 5 7600, and DDR4 for the 5800X3D.
