What's the difference between the snapdragon 801 and 805? Edit:difference found!

[WelshBloke]

Sorry I'm being lazy. (actually I've cracked a rib and am hopped up on painkillers and can't be arsed to get out of bed!)

I just got hold of an S5 and it's got an 805 rather than the 801 (was going to get a note 4 but I think Phablets are just a bit too big for my taste).

Is it likely to have any better battery life?

Edit:

Heres a bunch of benchmarks FWIW.

Antutu

3D mark

basemark x

Those are on a stock phone thats set up to do everything it normally does, nothings disabled and its doing all the normal syncing stuff in the background.

oh yeah it should provide better battery life over 801. Most importantly a much better GPU.
That's a surprise. I didn't know they used the 805 inside Galaxy S5.

Cool. I'd run some benchmarks if any has any they want run (I have to say that I'm not bothered by them myself but if you want some...)

I didn't either! It's apparently an LTE-A model that's being given out in the UK (and possibly the rest of Europe) at the moment. Its a straight replacement and it's just going out as a regular S5 as stocks of the old one run out.

For the regular S5 they used the Snapdragon 801. But Samsung loves to do really confusing things, so they released a Galaxy S5 4G+ (or LTE-A) that has the 805 with a QHD screen and a different camera module. That LTE-A version wasn't released in the US.

This has the regular screen and camera (I think that the cameras the same anyway, the screen definitely is).

It does have LTE-A support (not that I get lte-a in my area :/ )

Yea, looks like yet another different model of the S5. So confusing. The Korean LTE-A one has a QHD screen, an upgraded camera module (same MP, but better module) and 3GB of ram.

Thanks. I shall peruse that now.

Edit: yeah I'd read that one before and it was one of the reasons why I was surprised that I had the SD805

It's not really that confusing I suppose. The vast majority of people won't notice the difference and it's not being marketed as anything different.

Isn't the 805 more of a tablet SoC? It lacks a cellular radio. I'm going to say it here now, but that was the same choice LG/Google made for the Nexus 4. The cellular radio was a separate chip connected via the USB bus that resulted in massive USB wakelocks that gave the N4 its terrible battery life reputation. Its likely what happened with early LTE phones too because Verizon was too desperate to push out LTE to advance its aging 3G network, that phones like the Charge and Thunderbolt used separate LTE chips which gave atrocious battery life also.

I'm a bit concerned about this Nexus 6 that everyone's touting. Maybe Motorola got the battery life down, but its always a risk when you go with an SoC lacking an integrated cellular radio. With that said the HTC One X+ did just fine in battery life with an Infineon modem.

according to Qualcomm, integrated modem is a possibility, dunno if it's going to perform worse

https://www.qualcomm.com/products/snapdragon/processors/805

Modem
Integrated 4G LTE Advanced World Mode, supporting LTE FDD, LTE TDD, WCDMA (DC-HSPA+, DC-HSUPA), CDMA1x, EV-DO Rev. B, TD-SCDMA and GSM/EDGE (when paired with 3rd or 4th gen. Integrated LTE modem)
CAT6 speeds of up to 300 Mbps when paired with 4th generation Integrated LTE modem, with support for LTE-Broadcast, and LTE multimode dual SIM (DSDS and DSDA)

4G LTE Advanced CAT4 speeds of up to 150 Mbps when paired with 3rd generation integrated LTE modem, with support for Qualcomm RF360 and LTE-Broadcast
RF
4th gen power efficient LTE multimode transceiver with Qualcomm RF360™ Front End solution for world mode bands, lower power and PCB reduction

Battery life in this seems fine. I've been hammering it in a selection of areas (some with very spotty cell reception) and its been lasting well over 16 hours. I'm off work for a few days now so I'll get a better idea soon but I'm not seeing any problem so far.

I assumed that they changed the SOC because this had an integrated modem that the 801 lacked.

801 has integrated modem no?

Yeah it's likely Samsung did a good job here with a separate modem integration, but historically many phones have had battery problems and also have separate modems. I know the whole causation correlation thing, but I think its a decently fitting explanation, particularly with the Nexus 4 when you see all those wakelocks.

Maybe Moto does it right here, but its definitely still a concerning thing to me.

 

[WelshBloke]

801 has integrated modem no?

Not one that supports lte-a, or at least one compatible with the one that we have here apparently. Otherwise why bother with a separate model?

What makes you say it's a separate modem? There's a dearth of information but logically the main reason they had to switch to this was because it has an integrated lte-a modem.

https://en.wikipedia.org/wiki/Qualcomm_Snapdragon#Snapdragon_805

The Snapdragon 801 that's used in the regular S5 has an integrated modem.

 

[WelshBloke]

Is basemark osii any good? It gets about 1235ish on that.

I saw some results once on Anandtech and its just questionable. The score was bad but the actual SOT on the device was great in the Anandtech benchmark. Anyway, I'm not saying the S5 LTE-A is a bad device in terms of battery, but that in the past some devices that used separate modems performed poorly. Glad to see Samsung executed well here.

Yeah but does it support lte-a?

That's the main difference between the two models of S5 we are talking about.

The 801 model supports lte, then they bring out the 805 model that supports lte-a. That's the only difference that the carriers here are mentioning (and they aren't making much of a fuss about that either) which would suggest that they have done it because the 801 model doesn't do lte-a.

Apparently Qualcomm have been planning integrated modems in the 805 from the start as well.

Lol at benchmarks. This is indeed a monster!

Lol at benchmarks. This is indeed a monster!

What does the regular S5 get? And what exactly does this benchmark tell us? I've never cared for mobile benchmarks because unlike PC benchmarks where I can see how a CPU upgrade affects specific tasks like encoding, mobile benchmark numbers don't do a very good job of conveying to me what exactly is faster/slower.

I agree with you about the benchmarks, I was just running them out of curiosity TBH.

Regular S5 apparently gets about 42k.

This thing comes out as the fastest phone in every benchmark I've run. I'll post some more later.

Congrats on the awesome new phone.

man! I can't wait for XLTE 4G+ LTE-A!

Bumpage for a couple of benchmarks in the OP

 

[TrulyUncouth]

Very interesting. I believe the Note 2 I currently use has a separate modem but the battery life on it is stellar.

The performance is a nice bonus over the usual S5. Are you sure its not QHD?

 

[WelshBloke]

Yeah it's pretty nippy, give a good idea what the Note 4 will be like as well.

Are you sure its not QHD?

It's definitely 1080*1920. Mind you my eyes wouldn't notice anything higher. Its a lovely screen.
