AMD ryzen cpu equivalent to Intel

does anyone know why oem R10 board 1st version does not support 5000 series Ryzen but 2nd version does.  Obviously not due to bios as there is one BIOS version for both boards.  some hardware deficiency on the 1st version but wish to know more of what is missing.

B350, B450, B550 after market AM4 boards all can support 1000, 3000, 5000 series cpu if there is BIOS update.  the older the chipset the more it needs BIOS update to support 5000 series Ryzen.

In terms of naming scheme,

a crude way to think of AMD Ryzen is that Ryzen 3 is counterpart of Core i3, Ryzen 5 for Core i5, Ryzen 7 for Core i7, Ryzen 9 for Core i9.

the #### is for the series, so there is 1000, 3000, 5000 series for AM4 socket, roughly equivalent to LGA1151 Intel socket all the way to Intel 8/9th gen.

Ryzen 7000 series for AM5 socket, roughly equivalent to LGA 1700 socket, Intel 12-13-14th gen cpu.

The Intel Core i7-7700K is the closest Intel equivalent to the AMD Ryzen 7 1700, offering comparable performance in gaming and single-threaded tasks, while the Ryzen 1700 excels in multi-threaded productivity due to its higher core and thread count. 

The Intel Core i7-9700K and i7-10700K are considered comparable alternatives to the AMD Ryzen 7 3700X, with the 3700X offering more threads and better power efficiency, while the Intel CPUs generally provide higher single-core performance and better gaming frame rates, though the 3700X is more suited for core-heavy productivity tasks like video editing

The AMD Ryzen 7 5700 competes with Intel CPUs like the Core i5-13400F, i7-12700F, and i5-1335U, but its overall performance varies depending on the specific Intel CPU and workload type. In general, the Ryzen 7 5700 is known for strong multi-core performance, making it excellent for multitasking and heavy productivity, while comparable Intel CPUs often offer superior single-core performance and potentially better power efficiency or integrated graphics

The Intel Core i5-13600K is the closest contemporary equivalent to the AMD Ryzen 7 7700, offering comparable performance in many tasks despite being a slightly more powerful and less power-efficient chip. For productivity, the i5-13600K often performs better, while the Ryzen 7 7700 offers superior power efficiency and potentially better value, especially when considering long-term platform upgrades on AMD's AM5 socket. 

The Ryzen 10 version 1/2 is due to lacking support in the microcode (AGESA) of the version 1.

The whole idea of the AM4 socket was to provide long term CPU support and therefore upgradability of the CPU without the need to also upgrade the motherboard and RAM.

However, that obviously does not apply to OEM's as you cannot put a Ryzen 5000 CPU on an R10 that has a Ryzen 3000 CPU.

Now considering the latest AMD socket is AM5 and the same idea as AM4 is behind it, as in multi-year CPU support, and Dell not offering AMD systems anymore, it could very well be that AMD has changed their OEM agreements to include the requirement to support the socket long term (through regular AGESA updates).

Now why exactly the R10 cannot simply be updated to a newer AGESA version, I think the closest we ever came to an answer was that there's not enough flash RAM available on the motherboard to contain the AGESA code.

I still don't think myself that this is really the reason, and the real reason is they want to sell you a new PC rather than you upgrading your existing one.

I would say you will never truly find out the why behind it besides "It's OEM"...

I should add to that also that I equally highly doubt you will ever see the fTPM updated to support some never games that require a certain minimal version of that for security reasons.

Because it would require updating the AGESA versions and it would result in additional CPU support because AGESA is a complete packages and you cannot pick and choose which modules you want to update and which ones not.

HP Omen sells a B450 mobo Moria that in theory can have bios upgraded to support 5000 but user found out there is no BIOS update.  HP then sells a slightly newer mobo called Hana which has B550 chipset.  Prebuilt is less inclined to provide bios update for new cpu for profit reason, like it was said they would rather customer buy a whole new pc.

Would it be possible for R10 user to replace the bios chipset to have a larger ROM for updated bios?

many games do not need the most state of art cpu and gpu.  push for benchmark champion and bragging right is one thing, just enjoying playing a game at reasonable quality is another.  the ryzen 3000 series cpu still can play good games coupled with older powerful gpu such as 1080 Ti which can be found for 125USD on sale.

faster cpu is not always needed.  still using i7-8700 to do daily work without issue.  was told by my IT if I upgrade to i7-14000 I would not notice difference in graphic display work I do.

In the past AMD ryzen had a reputation of better value for price, but this has eroded over time.

AMD AM5 new 7000 CPU has become pricy to catch up with the Intel greed level.  the slightly older 5000 is not much better on used market either.

@redxps630​ No, even if you would replace the flashram with more capacity, the BIOS is digitally signed and you would also need the updated AGESA version and it would just not work.

Easiest thing to do is get a new motherboard and salvage from your R10 what you can.

And with PBS now being enforced that means your CPU cannot be transferred either.

That makes the issue even worse.

Luckily I pulled mine apart prior to them enforcing PBS, so I was able to use my CPU in another system.

seems PBS was enforced with later R10 bios.  I had a chance to do a deal with a no POST R10 but it was the earlier version so a no go.
