[SOLVED] 8gb 256bit RX580 -vs- 6gb GTX1660

[rocknriter]

I am building a photo editing and graphics painting system and requesting your input on two budget cards. I can’t understand why the 6gb 192-bit is more expensive than the 8gb 256-bit card. I assume the higher the memory, etc. the better the card. But that must not be the case. Please tell me why my assumption is wrong.

APPROXIMATE PURCHASE DATE: Next month BUDGET RANGE: USD $200-$250

USAGE FROM MOST TO LEAST IMPORTANT: System is being built specifically for photography and graphics editing using Adobe Photoshop CC and other related programs. There is no intention of using this as a gaming box.

CURRENT GPU AND POWER SUPPLY: Considering a Corsair or EVGA 650W or higher power supply. And the two following GPUs….

MSI Radeon RX 580 DirectX 12 RX 580 ARMOR 8G OC 8GB 256-Bit GDDR5 PCI Express x16 HDCP Ready CrossFireX Support Video Card Price: USD $209.99 (Newegg)

MSI GeForce GTX 1660 DirectX 12 GTX 1660 ARMOR 6G OC 6GB 192-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card Price: USD $239.99 (Newegg)

OTHER RELEVANT SYSTEM SPECS:

• CPU: AMD Ryzen 7 2700 3.2Ghz
• Mobo: Asus Prime X470 Pro AM4
• Memory: Corsair Vengeance LPX 32gb DDR4 2133 (PC4 17000)

PREFERRED WEBSITE(S) FOR PARTS: Newegg or Amazon COUNTRY OF ORIGIN: USA


PARTS PREFERENCES: I have no parts preferences. I am looking for the best quality and performance within my budget of USD $200 - $250. Therefore, if anyone recommends other brands I am open to suggestions.

OVERCLOCKING: No
SLI OR CROSSFIRE: No

MONITOR RESOLUTION: 1920x1080 with DVI-D and HDMI and VGA connections

ADDITIONAL COMMENTS: I am not interested in a large footprint. I would like a card that fits in most ATX cases. Number of fans desired: 1 or 2. Not 3. Also, I am unsure about the power needs. Will the card require a separate power cable to be connected or will it collect its power from the mobo?

the GTX is slightly faster than the 580 despite the fact is has more memory. 1660 has a newer GPU architecture, more efficient cores

results are for the general idea only, but you get the gist.
at your resolution I suggest the cheaper rx 580.
I suggest a dual fan card. a single fan card is one fan away from death.
the cards will need either a 6-pin or a 6+2 pin (aka 8-pin) cable or both for additional power.
the slot can provide 75W to the card the rest will need to be fed through the cable from the PSU.

which EVGA or Corsair you looking at they both sell some stinkers?

Thank you R_1, Looking at the specs in your link it appears that the only thing the 580 does better is with texture details. The 1660 outshines the 580 in everything else.

The PSUs I am considering are:

Corsair - RMx750x or RM650
EVGA -- SuperNOVA 750G+ or SuperNOVA 650 G3

I surely appreciate the link you provided. I've bookmarked it for future reference as it appears to be a very useful resource.

those are the good ones, and either would serve you well.
