I don’t know what the usage would be on a typical consumer machine these
days but my main ;point is that many people seem to think that when you are
buying a computer, you need to worry about NVDA. While I can’t talk about
bottom of the line machines, and I suspect it would work well with Eloquence or
E-speak or other undemanding synthesizers, I don’t thinkk most people would have
to worry.
You may have helped substantiate what I’m saying but what I’d be curious to
know is how much usage is shown for a current or recent machine, let’s say a
laptop or desktop in the five or six hundred dollar range.
Also, if you use demanding voices, I wonder how responsiveness changes as
the speed of the computer increases.

Hi Gene,
I have a top of the line mobile processor in this notebook. An AMD R7 Ryzen
4800H, with 8 cores, 16 threads, that can boost to 4.4 GHZ on all 8 cores. On
this machine, NVDA CPU usage never exceeds 1% mostly.

Not at that kind of useage. I don’t knoww at what point lag might
result, perhaps eighty percent, certainly at one-hundred but six to ten
percent poses no problem.
Also, the figure I’m giving is for my computer, about eleven years old
and at that time, a moderately powered machine. I have no idea what the
figure would be for modern machines. Perhaps in moderately powered
machines now, the usage would be perhaps three percent.

What you don't realize though is that causes CPU lag, and throttling,
which lags synthesizers when combined with other applications, such as
browsers. Even antiviruses don't use that much processing power with realtime
protection. This is very much so with synthesizers like eloquence. That is why
it makes sense to bvuy the most powerful specs that budget allows to prevent
this from occuring.

I'm sorry. 6-10% CPU power is alot of system resources.

Nothing I’ve seen convinces me that NVDA itself uses a lot of
computing power. nor have I seen this with screen-readers in general
to the small extent I’ve checked. Its using the newer synthesizers
that uses a lot of computing ;power. If you want to use the newer
voices, I can’t comment on the minimum specifications to get good
performance but in the old days, I had machines that today would be
laughably underpowered, running Windows 95 and Windows 3.1 and Via Voice,
very similar to Eloquence, ran well. This was in a 166MHZ, not GHZ,
Pentium machine and in an even older and less powerful machine running
Windows 3.1.
As for NVDA using a lot of computing power, if I monitor use when I’m
typing text with carachter echo on in the Windows Task manager, I get low
numbers. I just checked and while moving up and down the list in
task manager, then pressing f5 to refresh the screen, I get a 6 percent
CPU reading. When typing in this e-mail message, alt tabbing
immediately to the task manager and refreshing the screen, I get a 10
percent usage reading.
I’m not saying there won’t be variations, but those
figures are close to what I generally get when I test doing these
things.
And I haven’t seen complaints about the performance
of NVDA from people using tablets.

I would do a minimum of 8gb of ram, and a current gen i5/r5. That is as
low as you should go. Even with those specs, NVDA is heavy on CPU
usage.

I'd invest a bit more for
additional memory and a better processor. You might also consider
a refurbished business-class laptop, which can be had at very reasonable
prices (or at least could prior to the pandemic - everything's getting
more expensive as supply is constrained).
