HI, Allan
G3PIY,
I still have a replacement part, sealed in box: a Seagate full
size 10Mb hard disk!
Sorrily I do not have anymore at least one of the many Cordata
8088 "portable" (15kg - 220Vac) PC I had these times.
I ran my first Packet Radio VHF BBS with two 5,25" floppies and
8088 CPU 256K RAM ...
Later, another Cordata 8088 ran as a terminal for the home made
Packet TNC .
Later substituted by a TAPR TNC (known as TNC-1); other Cordata,
and later on for many TNC2 operating as Net Nodes.
Then endly, as the mess and no rules rised, I did QRT all, VHF and
UHF net and BBS, and went to a Pactor II HF Terminal with a
wonderful SCS-PtcII ...
It was many years ago, but a good age, until the mass come in,
destroying all with bad operating techniques and giant egos ...
It was at the beginning called "Packet Revolution" but sorrily
became quickly "Packet Involution".
Amen!

otherwise the manufacturers would go out of business.
I remember building
a “state of the
art” computer donkeys years ago. It had a mind-numbing
133MHz Socket 7 processor
and the RAM was £1 per Meg.
The customer managed
to raise enough cash
for 132Meg and an enormous 500MB hard drive with a new
fangled IDE interface completed
the package.
Windows 95 came on a
box full of 3.5 inch
floppies.
I still have the
hard drive from customer’s
older IBM machine, a Seagate ST-406, 5MB.

As another poster has commented,
comparing Intel processors across the
generations can be dangerous. Being that the main thing
you're looking to
do is run high-powered SDR software, I'm afraid you
cannot do it on the
cheap. SDR-Radio is a quite intensive program simply
because it has to
be. It's processing 2Mbps or more of data, running gobs
of Fourier
transformations, etc. That's why CUDA is so important
as the deep
computational algorithms are offloaded to the GPU.
You mentioned an Intel Core i5-4570. That is a
processor from Q2 2013, so
it's six years old. From the 4 in the model number, you
know it's a 4th
generation variant. Intel is currently shipping
generation 9, although
that's relatively new. Generation 8 chips are still
being sold across all
manufacturers. As a general guideline, for doing heavy
math, you should
not go more than one or two generations back.
A CPU from 2013 is just not suited for top-end software
from 2019 like
SDR-Radio.
The CUDA/GPU benefit is significant, but you can get
around it by paying in CPU
usage. I have one computer with a Nvidia GPU and CUDA
and a Microsoft
Surface, which uses Intel graphics. When I run
SDR-Radio on the machine
with CUDA, I barely know it's running. When I run it on
my Surface, I'm
generally around 25%-40% CPU usage, depending on how
much data (bandwidth) I'm
processing. It's not a sin to have moderate to high CPU
usage, and I'm
not affected in my other work. But I do take a
significant hit by not
having CUDA.
If you want the best for SDR-Radio, buy a modern CPU
(look at an AMD Ryzen) and
absolutely get a decent video card. I wish you the
best! I realize
that isn't the answer you're seeking.
