Difference Precision Boost 2 and Precision Boost Overdrive

[teecee5]

Currently thinking about getting the Ryzen 2600 or 2600x.
I am not planning to OC manually.

Still looking for whats the difference between PB2 and PBO.

What do I get more when I buy the x variant (which supports PBO)?

If PB2 is enough (PB2 seems like very good automatic OC in this article) , I could just buy the non-x and safe some money (150 vs 200€ in my country).

 

So whats the difference in PB2 and PBO? (and what is even XFR?)

Regardless of these features, the 2600 with a better cooler is arguably the better choice. I helped my gf with her new 2600 build and applied a 3.8 all core overclock which is a bit toasty on the stock cooler, but it performs very well. Add a better cooler and 4GHz should be doable at decent temps, perhaps even with a hyper 212 class cooler.

I would use the aftermarket cooler Scythe Katana 4 (LINK) for the Ryzen CPU.

Maybe even replace the fan on the Scythe cooler for a better fan.

 

edit:

I also read that the x variant is on average better binned, why I also tend to get the x?

I would only OC with PB2 and stuff, wont go into manual OC, so x-variant should get better clocks?

 

Is PB2 / XFR only for the x variant? or does the non-x support it too?

edit: all ryzen 2000 have them

I don't know what all those marketing terms mean exactly, but XFR is extended frequency range, and I believe that is the "boost frequency".

 

The 2600 has a max boost clock of 3.9 GHZ (one core I think), while the 2600x has a max boost clock of 4.2 Ghz on one core, or 4Ghz on all cores. Without manual overclock, the 2600 will NOT boost as high as the 2600X, so NO, they are NOT the same performance without manual overclock!

 

I don't know... people always say: "Oh the X versions are a waste of money." That may have been true when they didnt come with a cooler in the 1000 series generation. Now, I think if you don't want to mess with manual OC, the X versions definitely are a good choice.

 

Whether the 50 EUR extra is worth the 10-15% extra performance to you, is up to you.

As I understand it -- XFR is what controls the CPUs speed and takes into account certain variables to set the speed.  PBO is what pushes XFR a little further than it would normally operate.

Oooh good to know!

Thought the Base and Boost Clock only apply when I leave it completely stock, but activating PB2 and XFR maybe boost to similiar clocks (not taking into account that x-variant may be a better bin)

 

So I will invest the 50€ to get the 2600x. Better Clocks and espescially better bin

Yes, XFR and PB2 are "stock" features in any case. But it is kind of an automatic overclock, but the 2600 only does it up to 3.9 Ghz stock versus 4.2 Ghz on the 2600X. 

 

Again, if you want to manually overclock you can theoretically get the same performance out of the 2600. But there are some caveats. Power draw might be higher, and if you get a bad chip, you might not get higher than 4Ghz or 4.1 Ghz, so in that case the 2600X would still be faster.

 

You also get a better cooler with the 2600X.

Wait, as far as I thought, PB2 and XFR are options that you manually activate ontop of the regular Boost (atleast it reads like that in the mentioned article in my starting post. LINK)

 

Stock cooler isnt that important, since I will reuse my old Scythe Katana 4. But I could atleast resell it to gain some money back

No I think PB2 and XFR are automatically enabled, just another word for the stock boost. PBO is what you activate manually.

 

I think they make all these terms way too confusing honestly. Bad marketing mumbo jumbo. At the end of the day, it is just boost clocks, and PBO boosts even further.
