The thread where you discuss everything CPU. Whether you are looking for an answer to a CPU related problem or you simply want to show off your CPU, this is the thread for that.
I'll start with a question; I'm thinking about picking out a 16 core Xeon on eBay for around $420, is it safe to buy from there? Do they have an stability problems/compatibility, etc?
>$420
For that price you're getting a CPU and some weed
>>54718006
Hahahah xd anon, nice meme
I'm thinking about upgrading my cpu for 'muh gaming pc'. I currently have a 4690K, 980 TI and 16GB of RAM. I'm guessing it's my cpu holding me back the most.
Any suggestions?
>>54717888
Has anyone experienced weird/wrong CPU temp readings from UEFI and from HWmonitor? They conflict with each other because UEFI says 58C idle while HQ says 38C idle. Z170 extreme6 board with 6700k.
>>54718199
fuck off troll, unless you're actually that retarded, in which case fuck off idiot.
>>54718199
Your CPU is definitely not the bottleneck, unless you are playing heavily multicore games.
>>54718278
Thanks for the help
Best Pentium M for lowest temps on a T42?
I currently have the 735 and a spare 755, but for what I use it for I would only really need a 1ghz processor.
>>54718300
Considering a 2500k is fine for 90% of games out today, you're gotta be retarded or trolling if you think your 4690k is holding you back.
>>54717888
got a old i5 520m that wont stop overheating to 60-85 degrees under load
redid the thermal paste but i think shes dead jim
32nm a shit
>>54717888
>I'm thinking about picking out a 16 core Xeon on eBay for around $420, is it safe to buy from there? Do they have an stability problems/compatibility, etc?
its extremely risky one seller from japan wanted to insure the goods for $22 so they didnt have to pay tax here (yeah right)
I wouldnt risk it either pay a bit more and buy from au or us/eu
>>54718339
That's legit fine anon. But I'd still recommend upgrading.
>>54717888
Never buy used xeons over 50$.
This means they're newer, and are for some reason for sale earlier than their usual commercial lifespan, which means something may be wrong.
New ones, go right ahead, used but a fairly new model = no
The idea behind buying up used xeons is that they're just old sever processors that get sold in bulk for dirt cheap, usually they're a few years old and will last a few more.
Kinda like Thinkpads.
Buying a new one for 1500$ is retarded, but a used 5 year old thinkpad for 100$ is the best value and performance ratio.
>>54718356
its only a dell studio 1749 thats 6 years old and i use for porn and casual shit i have a real pc for games and shit.
>>54718339
that's nothing senpai, my i5-2520m hits 85-90c during 720p60fps youtube.
>>54718393
oh shit haha when i took it apart the stock thermal paste was cracked and try and whoever built it put a teaspoons worth all over the cpu and gpu and it got so hot it melted the little plastic shroud around the cpu
all fixed now and running like a top just gotta put it back togetther
>>54717888
Is time to buy the Xeon E5 2670 anons, for 110€ you have a fucking beast.
>>54718441
>300usd+ motherboards
>DDR3
>boost clocks a shit only on 1-2 cores
Nah its a meme cpu wait for the newer e5's to drop in price as they get replaced in the next couple of years not worth the risk
>>54718452
>talking shit about ddr3
DDR3-2133:
Latency 9-11-9-28 1.65v
DDR4-2133:
Latency 15-15-15-35 1.2v
>muh turbo boost and muh lower ram voltages
For boost clock, crank up BCLK, pussy.
For ram voltage, the difference is literally 7 watts.
>>54718665
Or spend the extra $30 for 3000Mhz+ with CL 16 and it will destroy both 2133Mhz DDR4 and any DDR3 with any timings.
Mtk6535p or mtk6580?
Which is better?
>>54718740
/CSG/ is that way
>>54717210
>>54718740
>Mtk6535p
1.3Ghz quad core, 64 bit
> mtk6580
1.3Ghz quad core, 32 bit
Also look at the RAM each device comes with.
>>54717888
Purchased for $ 239 on Ebay in 01/2014. New and in the box.
It is an i7 4770 with more 100 MHz base clock, disabled IGP and haswell refresh.
>>54718811
6735p is 1ghz tho
>>54718750
Isn't this the cpu general?
>>54719019
Yup but it's chinkshit, literally no one in here will have any real advice to give you. Desktop CPUs are NOTHING at all like ARM CPUs.
4790k masterrace though.
>>54719035
>making an implication
>>54719019
Are you going to:
1. Need that extra 300mhz
2. Need more than 3gb of ram
3. Ever do anything more with it than just shitpost on 4chan and watch YouTube?
>tfw waiting for zen
>>54718441
Wait for zen or get this
How futureproof is the i5-6600K?
How relevant is hyperthreading for games at the moment and what do you think how relevant it will be in a couple years?
>>54719428
https://www.youtube.com/watch?v=EhaB1dqYv_I
TL:DW: An i7 has a minor impact on average framerates and a moderate impact on minimum framerates.
>>54719694
for right this second sure, however with DX12 and Vulcan you can fully expect better core utilization as time goes on.
I have a 2500k and need a motherboard, would any h61 motherboard do? I'm planning on buying the cheapest (ASrock).
>>54719726
If you do not overclock which is retarded not doing so with 2500k, it will do.
>>54719754
Can you not overclock with most boards, can you recommend one for someone on a tight budget?
>>54719768
Only the Z series allow overclocking.
And since the 2500k is pretty old at this point, Z series motherboards aren't cheap.
You're honestly pretty fucked lol
>>54719792
P67 also allow overclocking if I recall correctly.
>>54719817
Yeah it's possible, they moved away from the P-series with Ivy bridge.
Actually he MIGHT be able to find an ivy bridge motherboard that supports OCing his 2500k.
B75 Q75 Q77 H77 Z75 Z77 I believe all support OCing of sandy bridge CPUs... I think.
>>54719849
Z75 and Z77 support core multiplier adjustments, the rest allows BCLK if supported by the BIOS.
>>54719973
Well technically the Q77 is the same silicon as Z77, so it COULD support OCing, but I doubt many motherboard manufacturers enabled it.
>>54720037
Nope, that has to do with the BIOS and none of the Q77 boards' BIOS allows that. Plus, Q77 isn't exactly the same as the Z77. It might be the same silicon, but the software built into it is different enough to have key features enabled that Z77 doesn't have.
>>54720101
the motherboard manufacturer can enable or disable the feature, early BIOS revisions of Q77 boards just used the BIOS of Z77 boards. But most later got updated because Q77 adds support for hardware virtulization passthrough and other business oriented features.
>>54718317
Whichever one undervolts the best. I had a pentium M that could run at 2ghz on 1.08v; normal voltage was about 1.2v
>>54720189
My 4790k can undervolt to ~1.05V, but it stops at 4.6 GHz, 4.7 GHz with a BCLK bump. Undervolting isn't a sure indicator of overclocking potential.
>>54720286
True, but he asked which one for the lowest temps on a laptop. My response was to pick one that can undervolt the lowest, as lower voltage @ same clocks = lower temps and a longer lasting battery.
>>54720322
I'm retarded and didn't read that post. My bad
>>54720333
nice trips though
What CPU would be best for a budget PC? I only have £100-120 to spend on CPU with motherboard
>>54720599
Used for light gaming and watching movies etc.
>>54720599
A Celeron N3150 motherboard
Or
An A8-7670K and a A78 MATX motherboard.
>>54720745
Do AMD CPUs not get v v hot? Even with cooling
>>54720792
Not really no. I think the only ones that actually get really hot are the FX-9000 chips, and thats because they're essentially factory overclocked.
The APU chips run much cooler, and can be easily handled with a Hyper 212+ or similar heatsink.
>>54720745
Could the Celeron cope with the occasional modern game?
>>54720792
If heat's a concern, then get an A10-7860K. It has a mode that limits the TDP to about 35W, yet can still beat the A8-7670K in iGPU performance. Or you can go with a N3150/N3700 embedded motherboard that has a TDP of just 6W.
A LGA1150/1151 Celeron and Pentium for comparable price is only better in single-threaded application, but you're limited with the number of threads it can handle at any one time. They're good for light gaming or moderate browsing, but not for both at once. The AMD APUs are a good compromise with a much better iGPU.
>>54720823
That Celeron can't, sadly. It's good for really low power consumption 1080p and low bitrate 4K streaming and some moderate browsing. It can handle most indie games at a pinch, though.
Likelyhood of dual socket motherboards that overclock when Zen rolls around? Always wanted an sr-2 type build.
>>54720868
Not likely. Summit Ridge is entirely a consumer SKU, which means that dual socketed boards are as likely as a non-Jewish Intel board member.
>>54720883
I wont say they wont come out, but they will be $350+ motherboards, even if it's AMD.
>>54720887
Summit Ridge only has support for one HyperTransport pathway (HTX3.1) as far as I can tell, and you'll need two for dual socketed motherboards (one HT bus per socket).
It's like how Xeons E5-1XXX can't be used in both sockets of a dual socket motherboards.
>>54720942
well the Zen architecture will be used in Opteron server SKUs as well, so i assume they will have a way for mutli-socket.
>>54721002
Yeah, but those are not Summit Ridge Zens. I'm certain they don't share the same socket either.
>>54721067
meh, i'll put $20 on their being at least one motherboard allowing dual consumer Zens in 2017.
>>54721087
Unless Summit Ridge does have support for more than one HTX3.1 bus, then I strongly doubt it. You can't just put two CPUs on a motherboard and expect it to work without the CPUs supporting multiple concurrent FSBs, Intel or AMD.
>>54721146
Well since summit ridge specs are unconfirmed it's kinda pointless to speculate.
It might have a single HTX3.1 bus, it could have more. No one but AMD knows for sure.
>>54721242
The fact that Summit Ridge is a consumer chip is the reason why I doubt it will have more than one FSB support. It's not a feature commonly used by consumers and it's fairly expensive to implement on die because it takes up a fair amount of die space.
I think AMD is planning a new socket for their enterprise, but it's possible that they might reuse the G34 socket for Zen, which is a completely different socket from AM3+ that Piledriver uses, of which G34 CPUs are derived from.
How long will my i5-750 last for, if games are currently the most demanding tasks I use my PC for? (I mean, I do work stuff as well, but have separate desktopa t work just for CPU heavy taks).
Im asking because whenever I ask for opinion about PC upgrade, everyone say "DONT BUY, WAIT FOR X". So I use the same PC since like 6 years and wait since around 3-4.
>>54721354
Best bang for buck new at the moment is the 5820k and a good motherboard. It brings you into DDR4 which should be with us for some time, most boards have Xeon upgrade potential, and USB 3.0 as standard. No real downside unless you want to save some power, which is not my concern as my power bill is rarely over 140/mo. Cost is about the same as an i7 skylake setup and in some cases cheaper, while having a longer theoretical lifespan as more games adopt better code for HT and accessing more cores.
>>54721310
Well there is speculation the Zen die shot the other day pictures the unannounced GMI multichip interconnect, obviously since GMI hasn't been announced and is only referenced in some *nix mailing lists by AMD employees, but if it is then we have no idea what the fuck will be possible in terms of multi-socket.
>>54721459
pic related, an educated interpretation of the Zen die shot.
I3 4170 or i5 4460? Some gaming some media playback
>>54721955
i3-4170
You can upgrade to an i7-5775C or 4790K (5775C is better for a mini-ITX case with no room for a graphics card) later and reuse that i3 with a C222/224 chipset mobo for a NAS build. i3s are compatible with ECC RAM, not the i5 or i7 for Jewish reasons.
>>54722292
I'm a bit of a noob with this shit can you explain NAS builds and ECC RAM ?
>>54722706
Im not him but I can help with the ECC part.
ECC (Error Correcting Code) Ram is memory that has additional hardware, both on the memory module and the CPU that allows for the detection and correction of single bit errors (and the detection of 2 bit errors, but not correction of them) within memory. ECC memory and Memory controllers have an additional 8 data lines (72-bit width vs 64 for normal ram) which are used to carry the ECC data from the extra memory chips on the modules, then process that data to ensure the other 64 bits sent during that clock cycle are what they are supposed to be.
This is important for anything involving storage (network attached storage, various raid controllers) as one fucked up bit in the buffer, be it the controller buffer or main system memory, can result in silent data corruption on your drives, and then you're fucked.
You might be asking: What necessitates the use of ECC? Well, manufacturing defects, environmental issues (heat, electromagnetic interference), and cosmic rays can cause single bit errors. The latter in particular is enough of an issue that pretty much every modern CPU made these days has ECC implemented into their cache design, and every server running at minimum has ECC memory.
>>54722706
NAS is a file server that's on 24/7. That introduces the possibility of errors as radiation from the sun actually interferes with the data that's on the RAM. Over a prolonged period of time, the chances of error forming increases because cosmic radiation is a constant. ECC has an extra parity chip on the middle of the DIMM that can actively check and correct those errors as it's detected, ensuring stability and minimal data loss/corruption over time. You don't need ECC RAM for your NAS or server, but it will improve the uptime and minimize the amount of data corrupted over its usage.
ECC RAM is only supported on C2xx and certain Xx9 motherboards on Intel's side and very specific AM3+ boards on AMD's side. If you put an ECC RAM in a Z97 or H170 motherboard, it will not work with the ECC functionality, but it will work as a regular (but overpriced) non-ECC RAM.
>>54722936
Yeah I looked it up earlier, it's not something I'm concerned with desu so should i just go for the i5 4460 since it's quad core ?
