4980HQ vs 6820HQ - 4980HQ = Way Faster ?? Intel Marketing

Just looking at the benchmarks, and it appears that the 4980HQ destroys the later 6th gen high end 6820HQ?

Am i missing something here?

 

The 6820HQ has higher memory and CPU BUS throughput, and more finesse in addition to being a lower TDP (AKA cooler chip).

Depends what types of computing you are looking to do and where your bottleneck will lie.
What's the point in having all that clock speed when your memory can't keep up with it to feed it fast enough?

Also 45 watts seems to be a reasonable limit for most modern laptops as far as thermal handling vs size vs mainstream popularity goes. What's the point in putting a hotter CPU in a chassis that will almost certainly throttle it lower due to lackluster thermal handling capabilities?

For mobile computing most consumers value battery life more than power. Additionally, most programs and applications a majority of users run don't necessarily need a ton of clock speed to behave satisfactorily.

 

What do you mean way faster?
They are around same performance.

 

It's just I have a 17 r2 with liquid metal on upgraded and undervolted a 4980HQ and was wondering what the performance is compared to my old 17 r4 6820HQ ( although i did OC this) and i was suprised.

Again, it depends what kind of computing you're doing and if you need single core performance or multicore performance as a priority.

Gaming vs rendering or crunching are completely different workloads with different requirements. I assume you're more into gaming which is going to prefer 2-4 cores at a higher clock speed versus crunching and rendering which prefer more cores (not necessarily at the highest possible clocks, but higher clocks will still be better) and higher memory and disk throughput.

It really depends where you discover your system as a whole is bottlenecked. In gaming it may never bottleneck on either setup so in that case the older gen setup with higher clock speed will be a better fit as long as your chassis can handle the heat.

We are at the point in computing where you need to really look at the system as a whole and not just individual component specs.

 

If you run cinebench etc. there won't be a big difference, idk why it says single core is so much better on the haswell, because it isn't. It's an error in computing the result.

 

Cinebench is less affected by memory bandwidth. IIRC, that Haswell chip was the first of the 128MB L4$ chips Intel made. Big boost to memory bandwidth (twice the bandwidth than DDR3 was at the time, and still a good ~25% more bandwidth than Intel's officially supported DDR4 speeds).

I think it was also among the last 128MB L4$ chips they made. Broadwell didn't do much to advance the breed, and the later generations made it more of a fast RAM buffer than a L3 victim cache.

Does all of that mean it's faster? Not really, since it's very workload dependent.

 

mine is between both lol http://browser.geekbench.com/geekbench3/8678713

 

In case you want to have more performance

 

I really posted more than anything to point out 1 is 4th gen high end and 1 is 6th gen high end.

You can buy a 17 r2 with a 4980HQ and 980M (Almost GTX 1060) for 1/2 that of a 17 R4 with a 6820HQ+ GTX 1060 (Not sure if they even do the GPU that low but you get the point).

I was surprised by how little the improvements are, yet some people who jump at the chance to spend a few thousand on a newer machine.

 

This isn't that unsual. My old haswell 4940MX performs better than your 6820HK for instance, in terms of CPU, not a whole lot has happened pre coffee lake.

But people will porefer the 6th gen due to DDR 4 ram, M2. ports, TB etc.

 

i would like to unlock it but i dont think Dell Bios can be modified. if you can i would be very grateful

@Danishblunt at this moment i have my 4710hq at 3.7 - 3.6 - 3.5 -3.5 (ghz)

 

It's ami aptio Bios, it can easily be modded. The flashing can be annoying tho, you might need a programmer for this mod.

The link is also rather useless, you need to backup your Bios with AMI
I believe you have an aptio V4 Bios:
download this to backup your BIOS

Open the programm, press on save, then it will backup your current BIOS.

 

Lol the results are not really in all cases correct. CPU boss isnt the most reliable to begin with but check the Geekbench 3 results.

But the 4980HQ was the highest clocked CPU on that generation in the HQ series. The 6920HQ isnt in this case, The 6820HK is its proper counterpart and can be clocked a fair bit higher than that. But if you had the 17R4 you had a variant with the 6820HK is think?

 

I don't think any 17R4 ever came with a 6820HQ, all come with a 6820HK which is "unlocked" and with some tweaking can beat the 4980HQ.

Plus it's Skylake, it'll run leaps cooler and with lower power draw compared to a 4980HQ, not to mention that haswell/broadwell mobile soldered have their long terms power limit set to 45w and you can't change that at all (except with TS powercut, not sure if it'll work on your model).

6820HK can raise power limit, on 17R4 it's limited to 100-110w (EC, not CPU) which is enough to achieve a high clockspeed if you adjust correctly.

@D2 Ultima

 

The above is right about the power limits

AHh i see now, yeah i must have got mixed up ! my 17 r4 was 6820HK too and i had that on 4.1 Ghz daily ran cool with liquid metal to be fair :
