ATI 4850 benchmark

[Max_87]

1. 4870 is using a bigger, dual slot cooler.
2. Fan speed is controlled by 4870 and not constant. Fan might be running at very low speed at idle.
3. "temperatures never rose above 82C since the fan would immediately spin up."
4. The readings are not comparable in the first place, we don't even know the delta T between ambient and GPU.
5. Different cards, different coolers, there are too many variables to compare anything.
6. In other words, it's pointless.

LOL

I wanted to reply, but then Max replied.

Thanks for the link Yukirin

NP, I am eager to learn anyway, since this is also part of my hobby. (Even though my work has no relevant to it >.<)

Very true. But I really wonder about point number 5 you stated. "Different cards, different coolers"

I've been wondering ever since my friend ask me this question, does each manufacturer of GC (Be it ATi or nVidia card) stock cooler have any difference in cooling the card ? Like some Manufacturer uses "Silent Fan", "Big Fan<ASUS>" or whatever what they call, when comparing with each other, how significant can it be ? I have no experience in this side of field so I can't really say much to him.


Btw, I think someone should change the Thread Title to HD4870/HD4850 Benchmarking
What do you guys think ?

Exactly my point where is the information on fan speeds .. auto .. manual 50% .. 100%??? When I run benchmarks I always have CPUID monitor running as well as EVGA precision/Rivatuner so all settings and temps are recorded. Otherwise whats the point?

If this 4870 running stock speeds can't stay under 82C with a dual slot cooler under any fan conditions I don't want it in my machine.

Also interesting your points on this Max considering you were quick to post unsupported benchmarks from other forums while trying to make a point. Where are the above parameters in those links?

Anyway I do agree with your points and Delta T will be used in any future reviews I conduct involving temps perhaps even a revision of the Hyper212 review

Quoted for teh lulz.

and yet you were questioning why 4870 has lower load temps than 4850?

Me posting unsupported benchmarks? Come onnnnn. I can say every benchmarks are "unsupported", even YOUR benchmarks. I don't know why you are being offensive here, but that post was directed at that table ALONE.

Let me make myself clear AGAIN. Only that table is pointless because the testing methodology doesn't provide accurate/meaningful results.

I trust results that came from proper testing methodology. Unlike someone who instantly discredit anything they don't want to see (and support the ones they want to see) regardless of the testing methodology.

Oh, and what parameters? LOL

If manufacturer allows the card to run at 82C, why do you care? They know more than any of us. They create specs, temp tolerance. We only need to adhere to them.

Like I always say, temperature doesn't really mean a thing, as long as it's stable.

We are a very meticulous bunch here. Nothing but the best in stringent methodologies (lab test equipment, testing). We only refer to a select few and we can almost detect any fallacies in testing. At the same time, we applaud and value quality testing. Unfortunately, anything short of that is half assed and misleading... We would rather not review something if we even remotely feel that we cannot deliver the very best in our methodologies. Very high standards.

Chai and Max are the two people I highly respect in terms of methodolgies. The three of us regularly chat about stuff and discuss points back and fourth. We reach a consensus on things after going back and fourth on things. True teamwork right there. But one thing you will never see present is bias and ignorance. Opinions? Always (and educated ones at that - not just childish banter).

lol temperatures are relative to ambient. Temperatures on their own are irrelevant. Delta Ts are relevant.
One cannot compare load temperatures mearly on load temperatures. Heck even my cooling setup would have a high load temperature if my ambient was 40C.

Load/Idle temperatures and ambient temperatures are two halves of the equation. Delta T is the result of the equation.

So what are the temps of it is a good question, but only if followed up with what are the idle temps. Incomplete information is as good as wrong information. Anyone telling you they have a constant temperature short of a proper lab environment is full of it (delta T testing with LAB equipment is the next best thing).

Anyone can write a newegg-like review/advice with minimal (or no) testing.

Whoever that still couldn't understand Chai's post, I suggest:

1. Copy down "If manufacturer allows the card to run at 82C, why do you care? They know more than any of us. They create specs, temp tolerance. We only need to adhere to them." on a paper.
2. Repeat 1000000x times.

Read my post and view the results again and your response. IF the 4870 has a dual slot cooler and the 4850 doesn't why is the idle temp on the 4870 higher? And then read carefully again and tell me why the 4870 temp is lower under load?

Math doesn't lie and those results make absolutely no sense so I suggest you read a bit more closely before LULZ

Maybe 4870 was running really low fan speed, or maybe it's not spinning at all? There can be so many reasons.
