- The Jan. 12th (1993) issue of ***PC MAGAZINE*** posted a rather astounding
- benchmark for the ***local-bus*** version of the ATI Ultra Pro. 13
- Winmarks, at a resolution of 1024 x 768.
-
- Pretty remarkable, for a card that only has 2MB VRAM, or not enough to
- support a 1024 x 768 x 24-bit mode.
-
- There's something very shifty about the text of the article. Nowhere in
- the section on ATI cards does it confirm this awesome 24-bit capability.
- It does mention this benchmark in the section about TMS 34020 based cards.
-
- Yet another part of the article said that ATI wasn't finished with the
- 24-bit drivers in time for the review, but that ATI expected 24-bit
- mode to operate at "one-fifth of full speed." Presumably that's
- one-fifth of the 256-color mode, which scored 18 Winmarks, so that
- would be 3.6 Winmarks for 24-bit mode. Which would make it as fast as
- the fastest TMS 34020-based boards, for $1000 - $2000 less.
-
- But if ATI's card could really do all of this, it would be a major
- groundbreaker for PC graphics. It didn't get that kind of billing in the
- article, so I think the score is a typo.
-
- So would anyone like to verify these nebulous claims? I have the
- following questions:
-
- 1) Does the 24-bit, 800 x 600 mode actually work at all?
- 2) Does the 24-bit, 1024 x 768 mode actually work at all?
- 3) Do either of these modes work without crashing?
- 4) How is the display quality of these modes? Good? Fuzzy? Laughable?
- 5) How fast is the display in these modes? Zippy? Pokey? Sluggy?
