You can spend 120 bucks to find out.

Thanks. How come there aren't any pictures available online? It's hard to believe that no one ever took a photo of a Tualeron 1500 if it really existed.

There are two 1500's listed in the Intel spec sheet, page 26.

If they were indeed released and available is another matter. It is also possible that they were called back, or were commissioned for a special customer ? If there are any in the wild they must be super rare.

No, I noticed.
My best, but least romantic, quess is that the 2x 1500 listed in the Intel spec sheet are the result of typing errors.
The SL6JV (1500 Mhz according to Intel) discussed in this article actually seems to be a 1400 MHz.

Thanks guys, I consider this CPU non-existent until I see a picture. I'll ask the seller in Doornkaat's link to provide a picture for me.

Hi (from Hungary 😀,
Finally are you found the 1.5 Celeron? SL6C5?
That spec is very interesting, because SL6C6 1.4 before than SL6C5 1.5 in doc

S-spec registration is:

SL6C6 SL6JV -> picture but looks like just 1.4

SL6C2 Pentium III RK80530PZ017256 1400 133 256 Socket 370
SL6C3 Pentium III RK80530PZ009256 1200 133 256 Socket 370
SL6C4 Pentium III RK80530PZ006256 1133 133 256 Socket 370
SL6C5 Celeron RK80530RY021256 1500 100 256 Socket 370
SL6C6 Celeron BX80530F1400256 RK80530RY017256 1400 100 256 Socket 370
SL6C7 Celeron BX80530F1300256 RK80530RY013256 1300 100 256 Socket 370

SL6JT Celeron BX80530F1300256 1300 100 256 Socket 370
SL6JU Celeron BX80530F1400256 1400 100 256 Socket 370
SL6JV Celeron BX80530F1400256 1400 100 256 Socket 37
Based on Intel document SL6JV should be 1.5GHz, but CPU-W marking with 1.4GHz and igorslab photo same 1.4GHz

SL6JP Pentium III RK80530KZ017512 1400 133 512 Socket 370
SL6JX Xeon BX80532KC1800D 1800 400 512 Socket 603 Socket 604
SL6JY Xeon BX80532KC2000D 2000 400 512 Socket 603 Socket 604
SL6JZ Xeon BX80532KC2200D BX80532KC2200DU 2200 400 512 Socket 603 Socket 604

So amybe produced some samples, or just database but finally Intel sales not approved
