+1 love it!.. Never seen that video. I think I have finally figured out "why" I seem to have lost my ability to "spell". I have been experimenting with using the Win10 Edge browser as well as the FoxFire browser under Lubuntu. My baseline browser for years has been Chrome using a free spelling/grammar add on called "Grammarly". So while Edge seems to be a perfectly good browser, it doesn't quite do the job that Grammarly does. I suppose I should see if it has an addon like Grammarly. Same with Foxfire under Linux, does it run Grammarly? Ah, more tinkering.... ;) Just hadn't looked. Mumble.... Yes there is a Grammarly for Edge & for Foxfire under Linux. Some of my work colleagues over the years have claimed I am "detail oriented." I look at issues like this and claim I'm not. Either that or I have a much higher standard for "detail oriented" than they do? Tom A proud member of the OFA (Old Farts Association). |

What would be interesting is to try to get an idea of either the theoretical or the practical production your gpu "should" be producing and see what changes would cause that to happen without slowing down your CPU production. If you ignore the difference in the performance between the Windows NVidia SOG app and the assorted AMD gpu apps the database at GPU Z makes says a GTX 75Ti runs at 179% of the speed of a Vega 8. Since my Gtx 750Ti regularly runs anywhere from 13+ to 18+ minutes under Windows, it sounds like a Vega 8 "oughta" run a task in a half hour or less? Where this analysis breaks down, of course, is on the question of just how "fast" the AMD gpu apps are compared to the SOG app? Does anyone have any benchmarks?

1 stick of 8GB DDR 4 RAM single channel I would expect that to have a significant impact on processing performance, particularly for the GPU. 2 modules of RAM (of the same capacity & timings) would give memory throughput a good boost. Grant Darwin NT |

On chip and discrete video performance can't be compared even for the exact same model & version hardware as the on-chip video will be limited by the overall thermal & cache limits of the CPU module, and even more so by the use of system memory for the on-die video compared to the use of Video RAM (GDDR- Graphics Double Data Rate) on a discrete card.

I think I understand your point. You are arguing that GPU Z is doing an apple and oranges comparison? From the reviews at Anandtech for running different memory speeds on two different AMD cpus with Vega 8 and Vega 10 GPU's it is pretty clear that the faster the memory chips, the better the cpus and the gpu's performed. They weren't testing single channel/dual/etc. Just differences in memory module speed. Holding all the other things the same (same MB, PSU, Monitor etc). So we have several confounding factors here. A difference in the software applications under windows. And the difference between the discrete video card memory speed and the integrated gpu memory speed. And the difference in thermal limits (that I think were addressed in the Anandtech article for the purpose of that test at least). So I guess we need to wait and see how things turn out. I hope a half hour task on the Vega 8 may be possible. Tom A proud member of the OFA (Old Farts Association). |

I just went and looked. It appears there are 41 machines out there running this hardware. AMD Ryzen 3 2200G with Radeon Vega Graphics [Family 23 Model 17 Stepping 0] 41 systems 3.95 cores 4.63 Glops/core 18.29 Gglops for whole MB So clearly it is working somehow/way.

So the question is. Based on the results I am seeing with James' machine, what needs to happen to allow the Gpu to "fly" and the cpu's to continue to run "Ok" or a bit better?
