T (SU7300) vs. (TZ SU4100)

As i understand it the differences in the 2 netbooks (in terms of performance) is solely the processor and amount of memory:

T
SU7300 - 3MB L2-Cache, Intel VT
4GB RAM

TZ
SU4100 - 2MB L2-Cache, no Intel VT, dual core
3GB RAM

Which of these will perform better?

 

The T because of more ram and the SU7300 has more L2 cache. I doubt though in everyday use you'll be able to tell the difference between the two in performance.

 

The clock speed is the same: 1.3GHz

@OP
The cheaper one will perform better(price/performance ratio)

 

SU4100 Does not have VT or XP Mode (XP SP3) virtualization. But you can only use this feature with the 7300(and the 2300) if you're planning to install/upgrade to W7 Professional or Ultimate.

 

does it count for games as well?
I own an acer aspire 5315 (pentium t2310 dual-core 1.46Ghz iclock 533Mhz eclock and 1MB L2 Cache). the problem is it comes with x3100 intel's pathetic solution for games and hi-def movies: x3100. it can not handle need for speed underground 1 with customized settings to MED. even on LOW, the video card manages to LAG several times when playing the game.
So my question is if I upgrade this processor to one core 2 duo, will that change anything? I'm planning on doing the upgrade coz I'm really disappointed with this machine. this is the comparison between both processors: http://ark.intel.com/Compare.aspx?ids=31728,32431,

as it clearly points out, t2310 and c2d t7250 DOES support the same processor socket.
the vcore is the same for both processors, and so is the max TDP.

will this upgrade change anything on gaming, coz I was told to do the upgrade because "the processor has more L2 cache size AND the speed it connects to the x3100 will be increased". is that just a rumor or will this really happen?

I need this to be very clear coz it's still a mistery...
thanks in advance!

 

@Rodox
This seems to be the wrong thread to ask. There is a x3100 thread in the gaming section. It might help more if you adjust your memory config. Dual channel helps x3100's performance.

Here is the thread:
http://forum.notebookreview.com/showthread.php?t=128777

It's a long read, but might clear things up.

 

Strange that the 2300 and 7300 has VT and not the 4100. I always figured they were the same minus the L2 cache size. Anyone know of the 2300 supports speedstepping? I don't really trust Intel's Ark site.

 

I thought 1.2gHz was the slowest speed the C2D architecture will drop down to when idle?

 

There's also SuperLFM which drops to 8x/2.
Whatever, it has been proven that speedstep doesn't gain any measurable amount of battery life.

 

not to mention that the information on the ark seems highly suspect.

 

So......what are the benefits of the dual core? what application(s) will it see the higher performance boost...if any

 

This is kind of an academic question. The single cores are phased out anyway so just buy a dual core model and you are done

 

Why is it even a technical problem to virtualize XP mode with the SU4100 anyway? Doesn't seem logical to me...

 

SU4100 doesn't support Intel VT while the SU2300 (according to ARK in which most people have stated that at this point, is suspect) and SU7300 supports Intel VT.

Of course, that I understand. Why is Intel VT even needed to get a XP mode enabled with Windows 7? Is Microsoft having contracts with AMD too to get that done?
I don't have a clue, but i would have thought, that an something like that is only software related = Windows 7 related. Hence my question about the technical aspect behind that.

 

If the Amd processor has AMD-V, then it can use XP mode.

 

Thing is, that it is not just software related. CPU must suport hardware virtualization, which in intels case is intel VT. And AMD cpus support AMD-V, so you can enable XP mode on them too.
Whitout all this stuff, virtual machines would run very slow and would be useless.

 

Question is, if that should be a dealbreaker or not.* I guess not - and the SU7300 is not available in Austria so far, so I'll stick to the plan and get the Su4100...


* for me it's probably only interesting for running some old games - very very rarely though. And i might get them to run otherwise, so...

 

Oh. Understood. -- Technically, there shouldn't be an issue whether or not Microsoft's way of allowing virtualized XP run on non VT (or AMD-V) enabled machines. (i.e. VMWare's products have worked this way for a LONG time, albeit slower, when there isn't a VT-enabled CPU/BIOS combination).

Chalk it up to Microsoft's decision requiring VT. The reason behind it, I couldn't tell 'ya but I'm sure Microsoft's "official" stance is "It's the only supported configuration." -- Similar requirements to Microsoft's Hyper-V is VT support (hardware assisted virtualization) and a DEP-enabled CPU/BIOS combination.

so? final thoughts on the two? speed comparison?

 

Assuming identical ram chipset etc you will see no real synthetic benchmark differences between the two. Real world will see a marked improvement in larger memory dependent applications and multithreading from the larger 3 meg L2 over the 2 meg L2. Now from what I've seen you get the true 4 gigs and dual channel, The larger L2 cache and possibly bluetooth. To me this justifies the extra $50.00 for the 1810T over the 1810 TZ...........

 

Hey guys I'm considering the two notebooks and was wondering with a different processor and 1 extra gig of ram, how much would that affect the battery life?

I've read awesome reviews on battery life if the T but am wondering if it's the same as the TZ

Merry Christmas

 

if you want a happy holiday dont buy acer
merry christmas

 

Why shouldn't I buy Acer? Maybe that would've been more helpful.
Anyways, any noticeable difference in the battery life with an extra GB of ram w/ a SU7300?

 

Haven't tested it myself, i am still waiting for my machine, but from what i read on all those threads here, the difference is neglectable, if there is even any at all!
Some might even argue, that due to the better speed step technology the SU7300 should get better battery life actually...

All in all: Su7300 is the better option. The UMTS support that comes with the 4100 is the only feature that keeps that processor alive, but if you can live without that - as i do - you can forget the 4100 completely and go for the 7300.

 

I just purchase the 5810TZ-4761 (su4100 processor) and I am fairly impressed with its ability to multitask, play blu ray and run virtual box with windows xp. The cpu does reach 100% easily though which can be expected. I usually have 3 or 4 apps open, antivirus in the background and 6 desktop gadgets running as well while downloading and playing music. I have created another log in account that was set up for less resources and 0 gadgets and icons on the display and no aero as well and other tweaks.

 

Looks like everyone's going to have to live without WWAN support because I seem to have bought one of the last of these 3G packages... .

I say this because the place I bought mine from (Alternate, Germany) took it off their sales list. So I contacted them and they told me that this specific package was labeled "end of life" by Acer...

To think I ordered mine in what was like a two-week window between "in stock" and "no longer available"... ouf.

But believe me when I say I'm happy I took the plunge when I did! I'm surfing on my commute to & from work at an avg of 1.5Mbps

theres no major difference except for the price.. better go for the cheaper one.. or change it newer i7 proccessors. If its for gaming u can notice no major change.
i am thinkin to go for SU4100 in alienware m11x. It got amazing Gcard.

cheers!

 

The SU4100's lack of VTx support is a major deal-breaker for some...

 

@traveller
what do we loose with that option?? and is it worth the 100$ increase in price??

 

Read the thread if you want your question answered since you didn't check

 

That's nonsense. I can run 2 Windows 2003 VMs on a 5 year old AMD sempron with 2 gigs of RAM no problem using VMWare

Just use VMWare or virtual box and you'll be fine... even single core chips from several years ago can run virtual machines just fine as long as you have adequate RAM

 

The 1810T's 7300 is also dual core:
