Intel C2D P7350 VS AMD Turion X2 RM-70--which is better??

A friend of mine is looking to buy a new HP Compaq laptop and is eyeing two versions of the same setup--with the only difference between the two versions being the processors--one with the Intel processor (P7350) and the other with the AMD processor (Turion X2 RM-70) I mentioned above. The Intel processor is 2.0 GHz and the AMD also has the same speed. She will be doing a lot of graphics work on the laptop...Is there a difference in performance between the two processors, and if so, how much? Which would better fit her needs? The graphics card coming with the setup is an ATI Radeon HD 3450, with 256MB DDR2 dedicated graphics memory.

 

One word: INTEL

Better performance, lower heat output, longer battery life.

YES. Intel it is...

I couldn’t find exact benchmark results of the two, but I did find a comparison between AMD Turion ZM-82 (2.2GHz) and an Intel P7350.
A summary of the results :

............| SuperPI 1M** | 3DMark06 CPU | Cinebench R10 Rendering Single | Cinebench R10 Rendering Multi
Intel P7350........26............1775...................2143..............................4053.............
AMD ZM-82..........44............1551...................1779..............................3338.............

** Lower is better

As you can see from the results even the AMD ZM-82 (which is obviously faster than ZM-80) is significantly behind Intel P7350 in synthetic benchmarks. However, in real life computing difference won’t be as significant as suggested by those benchmarks, nevertheless P7350 is certainly the better CPU between the two.

 

Yep, ill second (really third) that.

+11 rep.

 

BTW, I'm curious: would you buy an Intel Core 2 Duo P-series or T-series for performance, never mind the heat issues or battery life...

 

Generally P series belongs to the new Montevina (Centrino 2) platform (1066MHz FSB) while T belongs to older Santa Rosa platform. But some new T series CPUs also come with 1066MHz FSB which led me to read more about it because AFAIK Intel 965 series chipset doesn’t support 1066MHz bus. So, if the newer T series chips are supposed to be run on the new Intel Mobile 4 Express series chipset, then what exactly is the difference?? you still call them Centrino 2 ??

For example both T9400 and P9500 have exactly the same spec(Clock :2.53GHz, FSB : 1066MHz, L2 size : 6MB, Package : FCPGA, Manufacturing technology: 45nm) except for thermal design power (35W vs 25W) , from what I see, that is the only difference this is very confusing.. Frankly I don’t think there is any performance difference between the two. But since P belongs to a newer generation, I'd pick that. But between T series chips having 800Mhz or lower FSB and P series with 1066MHz (given same clock and cache), P is definitely better.

Sorry for not being able to give you a definite answer, I'm a little confused about it myself

 

The newest Intel chipsets (GM45, PM45 and GS45) are currently offered with the following processors-

T3200- 2.0GHz, 667MHz FSB, 1mb L2, 35W TDP (Pentium Dual-Core)
T5800- 2.0GHz, 800MHz FSB, 2mb L2, 35W TDP (Core 2 Duo- "Merom")
T5900- 2.2GHz, 800MHz FSB, 2mb L2, 35W TDP (Core 2 Duo- "Merom")
*these are manufactured using the older 65nm process/technology.

The following are Core 2 Duo "Penryn" processors which are manufactured using a smaller 45nm process, faster FSB and more L2 cache memory-

P7350- 2.0GHz, 1066MHz FSB, 3mb L2 cache, 25W TDP
P8400- 2.26GHz, 1066MHz FSB, 3mb L2 cache, 25W TDP
P8600- 2.4GHz, 1066MHz FSB, 3mb L2 cache, 25W TDP
P9500- 2.53GHz, 1066MHz FSB, 6mb L2 cache, 25W TDP
T9400- 2.53GHz, 1066MHz FSB, 6mb L2 cache, 35W TDP
T9600- 2.8GHz, 1066MHz FSB, 6mb L2 cache, 35W TDP

The performance increases as clock speed increases, IF all other factors are equal. In the case of the 2.0GHz models, the P7350 outperforms the T5800 which outperforms the T3200. Despite having the same clock speed, they have different FSB rates and differnent amounts of L2 cache- both of which impact performance.

The T9400 and T9600 outperform the P7350, P8400 and P8600. The T9400 and P9500 are identical performance-wise, except the P9500 uses less energy and costs a bit more.

The only question mark would be the T5900 vs. the P7350. The T5900 has a clock speed 0.2GHz faster, but the P7350 has a faster FSB and more L2 cache.

So...it's tough to make a generalization about the T- or P-model being the better performers. Truthfully, any of the Penryn processors are exceptional performers, whether they have a T- or P-model number!

 

Thanks for your answers to my processor questions, people! My friend is going for the P7350, and will get her new laptop tomorrow. Many internetz and reps!

 

A little belated, but I've only just found this thread via Google. There is just too much platform-love of late from the Intel camp, so I thought to throw this in for some balance. Without further ado, this is the REAL score of the notebook you just got per the Intel guys' advice.

Compaq CQ40 Intel model
3DMark06 max: 973 Points
Cinebench R10: - Shading max: 1185 Points

And this is the other guy.

Compaq CQ40 AMD model
3DMark06 max: 2112 Points
Cinebench R10: - Shading max: 2654 Points

 

Bad Cyborg,

Your data is skewed. The Intel notebook you spec-ed has X4500 graphics, and the AMD one has ATI graphics, so the ATI is sure to win in 3DMark in this case.

If you give both laptops ATI graphics, the Intel one will win. The original poster stated that both laptops have ATI Mobility 3450 graphics.

 

That is an irrefutable fact. However, if you'd paid any attention to the Compaq line of notebooks, particularly the CQ40 series, which is no doubt what the thread-starter was referring to, you will see that there is no Intel version in existence that comes with ATI graphics.

I wouldn't be so sure about that because thread-starter did specified HP Compaq.

 

Intel, no doubt.

I would take P series over T. (More efficient)
