OK. I read that a few times. If I want to use the onboard video I have
to have a certain CPU that supports it? Do those have something so I
know which is which? Or do I read that as all the CPUs support onboard
video but if one plugs in a video card, that part of the CPU isn't
used? The last one makes more sense but asking to be sure.
To use onboard graphics, you need a motherboard that supports it, and
a CPU that supports it. I believe that internal graphics and an
external GPU card can both be used at the same time. Note that
internal graphics solutions typically steal some RAM from other system
use, while an external GPU will have its own dedicated RAM (and those
can also make use of internal RAM too).
You can usually set the amount of graphics memory in the BIOS, depending on
your need and RAM budget.
The 7600X has a built-in RDNA2 GPU. All the original Ryzen zen4 CPUs
had GPU support, but it looks like they JUST announced a new line of
consumer zen4 CPUs that don't have it - they all end in an F right
now.
Yup.
G-series: big graphics for games n stuff, over 3 GFlops
F-Series: no graphics at all
rest: small graphics (around 0.8 GFlops max), ample for desktops and media
X-Series: high performance
non-X: same as X, but with lower frequencies
The X series are boosted to higher frequencies which give you a bit more
performance, but at the cost of disproportionally increased power
consumption and thus heat. They are simply run above the sweet spot in order
to get the longest bargraph in benchmarks. You can “simulate” a non-X by
running an X at a lower power target which can be set in the BIOS. In fact
once I have a Ryzen, I thing I might limit its frequency to a bit below
maximum just to avoid this inefficient region.
But I’ll be buying a G anyways. Its architecture is different, as it is
basically a mobile chip in a desktop package.
As to the qestion about 5/7/9 in the other mail: it’s just a tier number.
The more interesting is the 4-digit number. 600s and below are 6-core chips,
700 and 800 have 8 cores, 900s have 12 cores or more.
The thousands give away the generation. AM5 is denoted by 7xxx. (Though
there is another numbering scheme that does it quite differently, like
7845H.)
