Is Sempron Cooler than Turion?

Hey guys - i have a question - I am about to exchange my
V4000t (Pen M) b/c it is simply to heavy/large for me.

I am going to get a v2000z instead online at hpshopping, however the Turions get very hot ( i had gotten a ml-30 a few months ago so i know firsthand). So if i get a Sempron would it run just as well as a Pen M? I dont care to have the 64 bit compatibility. I need a processer that will run similar to the Pen M (which i am currently using in the v4000t - it runs very cool). So if someone has a sempron please tell me about it.

Also is the the Sempron 3300 really much better than the Sempron 3000?

ANother question is about the bluetooth - i dont currently use anything that i would need blue tooth for, but maybe only for a wireless mouse perhaps. The regular wireless mouses have a usb plug in piece, does the bluetooth mouses not need one? then i may consider gettin the bluetooth internal aswell.

thanks

 

Yep, the Sempron will defineatly run cooler than a Turion, but I'm not sure if it'll run cooler than a Pentium M. It also depends on the notebook itself and how well built its cooling system is.

For example, my last notebook had an ultra low voltage Pentium M, so I expected it to stay quite cool, but I was totally wrong. It would heat up pretty quickly and the fan would sometimes run constantly....

I hope you can find your perfect notebook, you seem to be having quite a bit of trouble finding the notebook for you.

If the 15.4" V4000 is too big for you, how about getting a V2000 with a Pentium M?

 

If you customize your notebook with an internal Bluetooth card, you won't need the USB Bluetooth dongle that comes with the mouse - just hook up the mouse to the internal bluetooth and you should be set to go.

 

There is no big diff. between both since they've same cache. 3300 only a bit faster

 

Semprons use less power (25 watts) than Turion MLs (35 watts); they are more like MT Turions.

 

Vassil is right. But there are more than just TDP. All these uses same 7.9watts when they are running at 800Mhz, and this is speed typically it runs unless you run something that is CPU intensive.

And also, Turion MLs undervolts much better than Semprons and as well as Turion MT. Out of worst Undervolters are Semprons as lowest (minimal) VID is 1.075v for semprons. RMClock can not go lower than Processors Minimal VID. For Turion ML series it is 0.8V.

Adding to that, because semprons has lower cache they tend to jump to next processor stepping when they encounter little more load. ( see one of the Tomshardware review).

So in the end, I do not think it will buy much heatwise, but it definitely much cheaper than Turion ML and you could get a Sempron 3300 cheaper than base line turion.

 

Chinna is correct. I have the Sempron 3000+ on the v2000z. The regular temp is 50-60 degree. I believe the fan kicks in when the temp raise to 55-58 (don't remember exactly, the BIOS is F.13), then the temp will drop quickly when the fans on until the fan stop at 50, then the temp would start picking up again. It occationally runs at mid and higher 60s for more CPU intensive task.
I also try undervolt the Sempron, it won't go lower than 1.075v but I can lower the max voltage (1.35v). However, when lower the max voltage (at 1.8GHz), it does effect the performance. Super PI was running many seconds slower. Not sure if this is the same for the case of Turion ML and MT.
I'd try install the MT when the 64-bits really getting on mainsteam if the lappy is still intact and not too old/slow at that time. Hopefully, the Turion MT/ML will be much less expensive at that time also

 

You cant really blanket all Semprons as being poor undervolters. They are the same as an ML series Turion but only have lower cache which decreases the power consumption. The voltages are the same. The Sempron 3000+ in my Acer is undervolted and runs stable 0.9V @ 800MHz and 1.250V @ 1.8GHz. I dont know why tempoct got such poor results but I guess it really depends on luck whether you get a good underclocker or not.

Regarding heat dissipation, the Semprons really do not differ much from the ML Turions. They consume less power mainly due to the lesser cache but the input voltage is the same. So the heat dissipation is in the same range as the Turion ML.

 

Sorry if it sounded like blanket opinion for all semprons, But what I read is, new Mobile Semprons( atleast since last couple of months) are coming with Minimal VID as high as 1.075, and as we know, RMClock can not go any lower than CPUs Minimal VID. But we should be able to undervolt well at full speed. I
do not know why tempoct is getting poor Super PI results, which has nothing to do with UnderVolting.

I also got this Semprons Minimal VID info from RMClock forums and RMClock author said it is because of new Semprons have high Minimal VIDs and RMClock can not really do anything about it.

But again, Initial batches might have come with same voltages as Turion ML, but later things have changed to improve the yield, or may be only specific batch was affected by this Minimal VID being as high 1.075v!?

I am just refering to new sempron processors based on info I have.

 

Uh-oh! Miner, I can't go under 1v with my setup on the Sempron 3000+ using RMClock. Can you tell me exactly how you do it? What driver do you use? I really like to make it run cooler.
Hopefully, this is not motherboard dependent.

 

Hey everyone - thanks for your info.
Heres the thing - price doesnt matter - ideally i want a Pen M - however the v2000z are turion or semp so i want which ever will run nice and cool like the pen m. I dont get this undervoltin/clockin stuff - id prefer not to mess with that and get whatever will be great w/o doing the undervolting. I dont
hear of anyone undervolting a Pen M... ?Or do Pen M's also need undervolting?

I would get a V2000 with Pen M but i'd much prefer the x200 over the intel 900.

I basically am trying to get the same size/specs of a v2000z but would like it to run cooler than a turion.

 

Well, I dont know whether newer Semprons can go under the 1V limitation. But if you follow the undervolting thread that should give you pretty much the instructions on how to undervolt with RM Clock. Suggest that you start off with the stock voltages and multipliers, so 4X @ 1.075V, 9X @ 1.350V. If you cannot go any further than the stock speed then trying increasing the multiplier to 5X and test to see if it works stable at 1.075V. This will increase power consumption over the 4X multiplier but might be a good trade off as you get 200mhz more at the same voltage. Remember to test it for stability every time you change the voltage. Repeat the same for the highest and any intermediate stepping you want testing each time for staility as you decrease the voltage. Your results might not be same as mine as each chip is individual and undervolting mileage varies. The motherboard might affect it but HP uses the same MB/chipset combo for both the Turion and Sempron based systems, so i dont think it should impede undervolting. I amd currently using AMD cpu driver version 1.2.2.0

Well, the Sempron will probably no run any cooler than the Turion. You could look for systems with the Turion 'MT' series they consume less volatge and therefore should give out less heat. But they are pretty rare and Fujitsu and Averatec use them in some of their models.

People do undervolt the Pen M. It's all optional. The V2000(with the P-M) in most cases will run as hot as the Turion based versions. My brother has a pentium M based V2000 and the cpu temp usually stays in the 50C range and can go as high as 65C depending on the usage. It has the usual hot hard disk which seems to be common among all V2000/dv1000/L2000 series. I dont know whether it is the design of the laptop(it is pretty thin) or what but they tend to run a bit warm.

 

I totally agree. These laptops are quite thin and when I'm working on my l2000 I can feel the HDD writing files just under my left palm. Cooling pads help a lot; if only we could find this PCMCIA cooling fan, I'm sure it would help with the HDD temps.
Yet, IMO the laptop is in no way hot. I still have to experience it in the summer but in autumn/winter I've had no problems

 

Wow if even the Pen M V2000s get hot then maybe i SHOULD just keep my V4000t - theres barely any heat given off by it - and its pen m... w/x600 (however i dont game!) The only problem is that its too heavy for me.

So i was going to get either the pen m or the sempron v2000. But those give off heat too and i am assuming that heat is a bad thing in a laptop right?

So fedex is coming in the next two hours to pick up this v4000 and i was going to get either:
V2000z:
Microsoft(R) Windows(R) XP Home Edition with SP2
– AMD Sempron(TM) 3000+ (1.8GHz/128KB L2 Cache)
– 14.0 WXGA BrightView Widescreen (1280x768)
– ATI RADEON(R) XPRESS 200M w/productivity ports
– 512MB DDR SDRAM (2x256MB)
– 80 GB 5400 RPM Hard Drive
– DVD+/-RW/R & CD-RW Combo w/Double Layer Support
– FREE Upgrade to 54g(TM) 802.11b/g WLAN w/125HSM!!
– 12 Cell Lithium Ion Battery


OR

V2000
Microsoft(R) Windows(R) XP Home Edition with SP2
– Intel(R) Pentium(R) M Processor 725A (1.6 GHz)
– 14.0" WXGA BrightView Widescreen (1280x768)
– Intel(R) Graphics Media Accelerator 900 - Pentium
– 512MB DDR SDRAM (2x256MB)
– 80 GB 5400 RPM Hard Drive
– DVD+/-RW/R & CD-RW Combo w/Double Layer Support
– Intel(R) PRO/Wireless 2200BG WLAN
– 12 Cell Lithium Ion Battery


Which one is better (less heat, better processor) or is almost as good as the v4000t?

thanks guys i need to make a decision in an hour cuz fed ex is coming to get this v4000!

 

V2000z. Get Bluetooth too if it's not too much more expensive.

 

so v2000z over the v2000 or v4000t? - Im concerned bout the v2000z turion getting too hot - 64 is not a concern.

thankss

 

also im not a big gamer but i would like to do some light video work so the x200 in v2000z may be enough to do so right - its going to be more capable than the intel 900 in v2000. (I know my x600 card in the v4000 is def a winner but i really wont need such a high end card)

 

I'd go with the v5000z over the v4000. HP shouldn't have had to have made as many cooling compromises with its larger form factor and its 200M has the 128MB of dedicated video memory option. Circuit City has some retail models of the equivalent HP dv5000z in stock, you might want to swing by one and see how hot the display model gets.

 

id prefer a 5 lb 14 inch notebook tho for traveling purposes - so its still between the turion or pen m v2000z or i just keep the v4000t??? i still cant decide guys! the v4000t has a pen m and x600 so im getting the best performance and low heat but im stuck with a heavier larger notebook. whereas if i get the v2000z its hotter and lower graphics and its the same price as the v4000! so i cant decide whats better.

 

radha, I understand how you feel. I went thru the same thing before choosing my V2000z.

take it one step at a time.
Is 64 bit important, no, choose Pentium M based laptop then. If yes, Turion based laptop.

screen size or weight more important? Screen size, choose 15.4 inch (V4000, V4000T, V5000Z). Weight, 14 inch (V2000, V2000Z)

Once you have narrowed it down... then Heat... Some say Pentium M is cooler, some says both are the same.

I say both are the same heat wise. It all depends on the laptop's design. V2000 & V2000Z run "warm" becoz of the harddrive. the V2000 series are small laptops making harddrive run "warm". the 15.x inch laptops have more space for heat to dissipate.

As for the CPU heat, again, I say the same. Both laptops run the CPU until a set temperature before turning on the fan.

One other question to ask for is power consumption. Pentium M wins here.

there are a lot of factors to consider... unfortunately, only you can decide which to choose.

 

I can succesfully set my max volt to FID 9, and 1.150v

without having any effect to my performance..

 

You are right you will be able to decrease Max voltage at higher steppings, but you can not go any further down than 1.075v at 4x, because that is minimal VID for the proc.

But again that may not be a great deal as savings at 4x is not that substantial.

 

I saw in the pics that you've set the AC mode to Maximal, which means you have turned off throttling. Just noting, this will increase the temp of the cpu.

 

My bad. I am able to get the same result now
Just realize that my previous test is not valid coz I was having more program running when lower voltage.
The temp is, indeed, reduce. Hopefully, I'll get better battery life too

 

this maybe true... in which I remembered that I was getting
Frequency = 1.80
Temperature = 59.0c ( CPU temp )
HDD = 53.0c

BUT

I Finally solved this temp problem by buying new laptop lap fan cooler and the temp dicreases 10degrees celcius.. WAOW..

I am now have a 41-43C steady temp for HD and 40-45C for CPU

the targus tornado fan for $9.99 at compusa -AR really works and does its job BEAUTIFULLY guys...

 

If you set AC Profile to Maximal, CPU will run at Full speed always on AC,

So you need to set AC Profile to Auto, that way CPU switches speed based on load. That once gives better temps with/without cooler.

 

You're rite, and I need cooler anyway.. especially when its on AC, and playin games with my 7200rpm HD... verheat:

 

I really liked your suggestion :hp:
