Best GFX Card for CRT Emudriver 2.0, supporting low clocks
« on: July 30, 2019, 07:04:46 am »
Hi!

Currently I use HD5450s with CRT Emudriver 2.0, although for Mame I use super resolutions  :applaud:, it is true that for other applications I use real low clock modes.  :notworthy:

I want to buy new graphics cards and I need them to be compatible with low clock modes.  :hissy:

CRT Emudriver 2.0 is compatible with many last generation AMD cards, as I have read any card that has analog output is compatible with low clock modes, is this true?  :blah:

Previously the best graphics card was the HD5450.  :cheers:

Today, What is the best GFX card (more powerful and compatible with low clock modes)  to use with CRT Emudriver?   :dunno

Thank you!

Arroyo

Two rescources :

AMD cards in chronological order:

https://en.m.wikipedia.org/wiki/List_of_AMD_graphics_processing_units

Graphics card benchmarks:

https://gpu.userbenchmark.com/

Itís easiest to get one with Analog output in either the form of a VGA (DB9), or DVI-I connection.  The most recent card to support Analog was the R9.

Newer cards will work using the HDMI output and buying a digital to analog converter (DAC).

There are newer APUís that have a VGA port and output analog but at this time arenít able to be controlled  by the AMD driver hack from Calamity, and as I understand it wonít be able to in the future either.

He's after information on the dot clock minimums, i think. And i'm going to have to assume "best" means most powerful.

I can confirm the 69xx cards will do sub-8mHz. I'm using them for 320x240 modes. Which probably means the 79xx series will as well, and that the early R9 280 cards might too..? Not really sure beyond that.

I am using an r380x via dvi-i port no problem..  really hoping we get support for the newest and cards just released.

At the 'top end' of there aren't that many.
In affordable and sometimes 'compact' form, easy to power, in second place I'd say the few R7 with either VGA or DVI, which I'd limit to GCN 2nd Gen in case FreeSync would be an alternative (plus groovy might be able to do 15khz feeesync, fingers crossed for that), therefore:
. R7 260, 260X and 360
And in first place the bulkier, more power hungry:
. R9 380 and 380X.
There are a few OEM alternatives but I haven't read any feedback. Also I'm not 100% sure this stops with the 380X but I couldn't confirm more powerful fitting models.

I don't know what your 'other applications' for low dot clock are, but even if the R9's are roughly twice as powerful as the R7's here on paper, personally I'm not convinced they make that much of a difference today.

Hi!

Thank you a lot!

Yeah I want the more powerful card supporting low clock modelines, we can do a quick list:

AMD Cards supporting low clock modelines:

AMD Radeon HD 69xx - Ok (with VGA or DVI-I)
AMD Radeon HD 79xx - Probably (with VGA or DVI-I)
AMD Radeon R7 260, 260X and 360 - Ok (with VGA or DVI-I)
AMD Radeon R9 380 and 380X - Ok (with VGA or DVI-I)

Just remember it has to be DVI-I because DVI-D won't do analog, and while you can use an HDMI converter or whatever it might complicate things if you use low dot clocks.

The R9 380X doesn't have DVI-I, only DVI-D

? It does... both the 380 and 380X do.

Hmmm, i thought the only examples listed with DVI-I but it turned out to be incorrect, just the sellers not paying enough attention. I can certainly find some pictures of cards showing a DVI-I port connector, where i swear i've never been able to before. Maybe it's just me :/

I have multiple 380x cards and they all have DVI-I; I have yet to find a 390x that does though.

Does ATOM-15 work with the R9 380X?

Well, the R9 380 has had problems, so I'd imagine the R9 380X isn't going to play ball either.
