It's ok. You can always check the TI-Planet review when it becomes available in English. Also as off-topic tip, if you are taking French you should read the news in English then in French :)

How was determined that it is an eZ80 in this new calc? You can verify it by running some code with eZ80-specific instructions. Or by making a program pulse the I/O port and measuring the signal frequency. You can determine the system clock frequency with this. (does not have the I/O port sadly)Another way is to dump the OS or one of the apps and see if it uses the eZ80-specific ADL memory mode.

Offtopic : Unfortunately TI-Planet is still quite sluggish and doesn't appeal me to browse it, even with a decent computer :/.

ontopic : Oh well, it's now pretty much on par with the Prizm now.

EDIT : comparing the CE and the G35 is a bit unfair IMO that it would  make the reader eventually bias to the CE because the color screen. They should have used the Prizm instead.

Edited for calming my temper.

Or you can check the TI-Planet news where Critor opened the calc. :P
That just shows an asic. It does not say eZ80

Ok, but then how does Critor know that it runs an ez80? Or is he just speculating?

Offtopic : what the hell with that site? Even with a fraking i7 I still only have like 10 fps! ><
TI-Planet went the complete opposite route than Omni for site design. They wanted to add character and functionalities to the site, while Omnimaga switched to a minimal design. With an account you can switch to a lighter TI-Planet theme, but as guest you have to switch back to the light theme on every visit.

EDIT : What the hell ,do they compare the CE with a freaking Graph 35+? It's like comparing a palm with an Iphone!
I think the 35+ was the FX-9750GII with a SH4 processor, right?

I think he is speculating based on the increased basic and plotting performance, but there does not seem to be any hard evidence or I must have read over it. It could still be an ARM emulating the z80 if no evidence is found for an eZ80.

If it was a Z80, then BASIC would probably rival CSE BASIC speed, because the calc has 150 KB of RAM.  Because the TI-86 had 96 KB and required some sort of bankswitching since the Z80 did not handle this much RAM, this caused its BASIC to run about twice slower than the TI-85, so the same would be true on the CE if it used a 25 MHz Z80, for example (I think Z80 can't go above 25, right?).

I have a 20MHz z80 and I think that is about the fastest one you can get.

Yes, when I requested that sample I took the fastest one I could find :P

Nope I have a g35+ and it's an SH3. Concerning my surprise, it's mostly because I would have compared the CE to the CG-10/20 and not a monochrome calc. It's va bit unfaire and biaising but well. Sorry for having shocked someone.

Ah ok, but then if it's a SH3 it should still rival the TI-83+ or even 84+ for BASIC speed. That said, I think both the CE and 35+ are around the same price range in France. He might have wanted to compare with other calcs of the same prices as he might have found that spending twice as much money on an fx-CG20 when it barely does more than the CE (and is in fact much slower for drawing commands). Also, I think the PRIZM lacks exact answer mode, but I could be wrong.

I'm unsure why Casio calcs are so expensive in France, though. Maybe because they are more popular there and Casio has some sort of monopoly there in some school levels like they do in USA? In USA, both the 84+CSE and Casio PRIZM costs $129.99, while in Canada the CSE is $159.99 and the PRIZM $129.99.


On the other hand in Canada the Nspire CX CAS is now $229.51 *.*

How is it unfair ?

The comparison with the fx-9750GII only deals with mathematics.
And from this point of view, fx-9750GII is the same thing as a Prizm fx-CG10/20.

Dream of Omnimaga

It was probably because the 9750GII ROM provides about 100 times less memory to the user than the 83PCE (28 KB RAM on a 9750GII ROM vs 3150-3222 KB (150 KB RAM and 3 MB Archive) on a Premium CE), and twice less total memory if flashed with a 9860G ROM, so Eiyeron probably considered its features and user specs much inferior to the 83PCE (the PRIZM has 16 MB of Flash). When comparing calculators, some people only takes technical specifications into account. On the other hand, Critor has a point, since the comparison, as he says, was only about its math features (in fact I don't think the PRIZM even supports exact mode, so for that it's actually inferior to the 9750GII)
