T6400 and RM/ZM

Was trying to scout BB for a Sony Z the other day and found some HPs with processors I didn't know anything about. I've gotten admittedly lazy about keeping up with the latest stuff for the last month or two but it's not been that long..

I tried to search around a bit but wasn't satisfied with the information I found.

So what's the scoop? RM, ZM VS. the old TL vs. the T6400 (entry level Penryn??)

T5800 is still the older 65nm stuff right?

 

RM = Athlon
ZM = Turion X2

The RM and ZM are part of AMD's new Puma platform, which breathes some new life into their aging Athlon and X2 CPUs. Read more about Puma in detail here.

You should avoid buying an RM laptop as the Athlon is not a true mobile CPU; it uses a very old architecture that is not well-suited for laptops. Wrt comparing the T6400 to AMD's offerings - I couldn't find any information on the T6400, and I don't think it exists; but, maybe I haven't looked closely enough.

The T6400 is not on Intel's December 28th price list. Where did you find it?

 

It's on a Dv5 at Best Buy. It definitely exists. I read something about it being Intel's new entry level stuff phasing out the T5800, but not a lot of info available.

 

QL = athlon
RM = Turion
Zm = Turion Ultra

And the t6400 exists it appears to be a 45nm t5800 to me. CPU world used to have a page about it but its gone now. It was 2.0ghz with 2mb l2 cache 800mhz fsb built in 45nm

 

It is a Penryn Core 2 Duo, more like a cut-down version of the P7350. It will be better than similar RMs/ZMs....

 

You're right, sorry about that mistake. I had a feeling the Athlon was not renamed as RM.

 

Thanks to all who replied!

Bog, does that mean the RM are okay or still bad? Sounds like QL are to be avoided then..

If anyone has a direct comparison between The new Penryns, ZM/RM as far as clock per clock performance, heat and power consumption, that'd be awesome.

 

The RM denotes the Turion, meaning that it won't have the improved HyperTransport, L2 cache, ATI IGP, or any of the other enhancements brought about by the Puma platform. It's essentially the same old Turion X2, repackaged.

 

This is incorrect the RM Turions and QL Athlons DO have the upgraded hypertransport and are configured to use the new ATI IGPs. The only difference between them and the ZM turion ultras is the cache; with the ultras having 2 instead of 1mb of cache and the QL athlon being slightly less power efficient. Remember how AMD mobile processor nomenclature goes Z M or R M is more power efficient than Q L or T L.

 

It exists. I ordered a 1525 with it. I was looking for a cheap laptop for web browsing, email, etc. for use here at home when I don't want to fire up my desktop.

Basic specs:

224-4115 1 Inspiron 1525, Intel Core 2 Duo T6400, 2.0GHz, 800Mhz, 2M L2 Cache
313-5773 1 Jet Black Color with Matte Finish
317-0169 1 3GB, DDR2 SDRAM, 2 DIMM for Inspiron 15
320-6047 1 15.4 inch Wide Screen WXGA LCDTrueLife for Inspiron 1525
320-6059 1 Intel Graphics Media Accelerator X3100
341-5617 1 160G 5400RPM SATA Hard Drive

It is not on the web site yet. The Dell rep found this in a catalog that has not yet been mailed. I got an incredible price on it and $100 in Dell Dollars that I should receive in 4-6 weeks.

I wanted a very inexpensive laptop and will not be traveling with it or playing games. It's just a convenience for browsing mostly. The 5400 RPM speed is not great and neither is the X3100 but it'll be fine for my needs.

 

Jesus, I need to brush up on this stuff. Just ignore all of my posts!

 

I just wish I knew more about the chip itself. I know it's faster that the 5800 but how much faster? What's it comparable to? Google search yielded next to nothing.

I build all of my desktops and that means buying the individual chips. I've never seen such an esoteric naming system before.

 

Check out the processor benchmarklist on notebookcheck...it has the t6400 listed. It is definitely a 45nm entry penryn chip that is replacing the t5800. The advantage of the 45nm will of course be better efficiency ie battery life. Speed should increase slightly but the biggest gains will be in power consumption. The t6400 should be fast enough for most average users. It is faster than the AMD processors because it has twice the cache at the ZM turion ultra and 4X the cache of the RM turion. Hope this helps.
