How to make a diff between cel533 and 533A?

[Dark]

I'm posting it here since i got no replies from the cpu forum...sorry if this is a newbie question 🙂
Thx for any help

If you mean the first gen. cel's the diffrence between them is this:
533-no l2cach
533a-128k full speed l2 cach
if you mean the 2nd gen cel's(celeron 2) i dont think there is letters describing them, but all celerons have 66MGz bus speed
(if im wrong it wont be the first time)
or you can visit http://www.anandtech.com/showdoc.html?i=1212&p=1

Well, there's no such thing as a 533 without L2 cache. If it's the 533A it should be denoted as such, or say Celeron II or Celeron Coppermine core, or some such thing. It is also FCPGA so it will have a bluish colored patch on the top of the CPU which is the core itself.

The difference between the 2 is that the original celeron uses 2.0 volts to operate at, and the Celeron II uses 1.6 volts. Also, the first celerons were fabbed on a .25 micron process, while the celeron II is fabbed on a .18 micron process. The celeron II at 533 mhz should be labeled 533A, but a lot of computer retailers and resellers are have labeled all celeron cpu's with the letter A since the introduction of the 300A, which makes it very difficult to know what you are actually buying. Those are the differences.

The "old" Celerons had speeds up to 533 MHz tops. The new Celeron II's (or Celeron 128's) have a Coppermine-like core and start at 533 MHz and go up to 700. To distinguish the old 533 from the new they add an "A" to the speed designation of the new Celeron II 533A. The higher speeds don't need such a designation, of course.

If you're going to get a Cele be sure to get a 533A or 566, which cost about $100. Avoid the faster Cele's since they cost almost as much as a P3 Coppermine. In fact I'd recommend you get a P3 cB0 stepping Coppermine 600E (which cost under $200 today), or faster if you can afford it. If you overclock the 600E you will have a much faster PC than if you overclock any Cele, on average, and it won't cost that much more than a Cele 533A or 566.

P.S.
Here's an Intel table of Celeron chips:

Thx all 🙂... what i meant is how can i make a difference visualy...to be sure they're not selling me a cel533 instead of 533A.
I saw the picture in anand article, it was 566's picture...am i right in assuming that the 533 a will have the same specs printed on the bottom (533A/128/66)?

Celly 533a is a flip chip like the cumines.. thin thin green board with a little square on top.

Only Intel could muddy the waters quite so much with a little "A"!!! It seems to fit into their so-called marketing plan, consumer confusion apparently working to their advantage.
As I understand it:
1. celeron 533 has silver metal cover on processor, about 1-1/8" square, older P2 core with 128k cache. Won't overclock worth a damn.
2. celeron2 533A has no metal cover, much smaller bluish or greenish exposed silicon processor, about 5/8" square, newest p3e core with 128k cache, looks just like any P3e. Excellent overclocker, your mileage may vary.
With more information about your system and what you want to accomplish, members would be able to be of more help.

FC-PGA celerons use 1.5v, not 1.6v.

 

[BuddyHolly]

Hey, don't forget about those critical extensions...how long has it been since I heard about 3dNOW and whatever Intel's version of the same is...

The FC-PGA looks kinda blue, about 1+ cm square. PPGA is bigger.

The Celeron voltages are higher with the faster chips (I think up to 1.65 V). Not all are 1.5 V.

CII has onboard L2, and now has SSE.

I think chip makes are not making their product clearly identifiable. Look at all of Intels letter designations. AMD did not give a designation for slot A T-birds that distinguished it from old slot Athlons. It is no surprise that there is confusion in the market!

If you put a 533 next to a 533A, they will look quite different. Just kinda hard to describe.
