Intel i7-5820K Extreme Hex Core CPU Processor (3.30GHz, 15MB Cache, 140W, Socket 2011-V3, 28 Lanes PCI Express Generation 3)

Running mines at stock because there's no need to overclock it. Destroys everything I throw at it; video rendering, multithreaded compression, gaming. Could probably do all 3 at the same time. I'm using mines with a Kraken X61 cooler, and it never goes above 50C unless I'm stress testing it. I idle at 34C. The only downfall with this chip is the X99 chipset and the motherboards. This is actually my second chip, as my first only lasted 5 months (due to motherboard faults). I was running the 5820k @ 4.0GHz on a Asus X99-S with Antec HCP-1300. During normal desktop usage, I had a fatal fault with my system. Upon troubleshooting, the PSU and motherboard AND processor was dead. There were no physical defects on the chip, or on the power supply cables (they're modular, I examined the used leads, no burns or charred pins. Replaced cables and nothing). If you google X99 VCCIN manufacturing fault you'll see results with all different motherboards and chips. I reached out to all 3 companies. Intel got back to me within 48 hours of my first email/RMA request during the weekend. I sent my chip on tuesday, and received a new chip on friday morning. Some of the best customer support I've ever received. Asus would not accept responsibility and would not provide an RMA on the motherboard as the serial key was not recognized on their RMA website?? They refused to RMA my board and told me to talk to my seller. Eventually got my refund after 2 months of chasing it up with an independent seller Antec did not respond to my RMA request or any emails within 3 weeks. I desperately reached out to Amazon as they sold me my PSU and they got me sorted out with a replacement within the same week. Very pleased with Amazon as always, excellent customer support with a very helpful representative.

5820k at 4.4Ghz with just 1.2 volts. Old single piece Noctua heatsink with a couple new PWM fans. I get just 75-80 degrees max as measured by Core Temp or Intel whilie in Handbrake/Intel Extreme stress-test. Temperature sensor doesn't play nicely with Speedfan, kept reporting much lower temps than Intel utility. I bought my 5820k in summer, 2015 so it is probably from a late manufacturing run and perhaps a little more efficient voltage-wise than most of the release samples. Had to use manual voltage to force turbo all the time as one app I use needs consistency. It eats Handbrake video encodes for breakfast, e.g. 1080p CRF14 x264 at 50fps+. For comparison's sake my previous Q6600 (which had fewer modern instruction sets ) would have managed about 2 fps at that quality. In other words, this processor exceeded my expectations and I can only assume the recent batches have been more efficient voltage-wise, or that I was very lucky. My chip is stable at 4.5 or more, but the voltage jump to around 1.26v required is too excessive heat-wise for my air-cooled PC as is, and I don't wish to risk shortening its life, have to spend more on cooling, or have water in my system. If you are in the market for a new cpu, you might prefer to get a newer cpu as Broadwell-e will likely be better.

Purchased from amazon warehouse for £269. I would normally be a bit wary of second hand processors but this has been rock solid since purchase a couple of months or so ago. Stable and low temps at base line but I did not really notice much improvement in benchmarks (3dmark) going from i5 4670k z97 platform. That said these are overkill for gaming. Read on if you are interested in overclocking / xmp: Overclocking with AIO on asus x99 a. A word of warning xmp profiles for ram rated over 2133mhz can can the blck and strap settings, this can have some unexpected consequnces. one would be poor system stability others I noticed were higer idle temps (as the cpu frequency etc were also changed) - this is different to the z97 where only the ram settings changed. I was unable to get the board to post with xmp on 3 different ram kits. (Currently using corsair dominator platinum 3333mhz.) It has taken me ages but I have a stable overclock of this and I have had to go mostly fully manual. That said it is running nicely at 4.5GHz with a ram speed of 2666MHz and I am happy with temps etc. So question is do the higher end processsors have the same issue, from a review I read I think not but I am not 100% sure. I would probably still buy this processor rather than the ridiculously expensive higher end alternatives however wish I had done my homework. Hope this helps others.

Been using this possessor for 1 month now. This CPU is almost 5x faster then my old 6 year old AMD Athlon II 620 x4! I bought this CPU to do a wide range of tasks but mainly for 3D Rendering. This CPU with 12 threads it indescribably fast at rendering images when my work is to much for my GPU's to handle. So far i have no over clocked it but have not needed but can apparently reach 4.5 if i needed a extra kick. If your gaming then it is obviously pointless to buy this CPU as the difference from my old CPU to this in unnoticeable in gaming. If you are video editing, 3D modelling and using software that can use 12 threads, than it is deffinatly worth it. One point, make sure you buy suitable cooling for this CPU. I had to go out a buy a H100i which keeps this cool at 28oC idle.

Este es el procesador mas económico de la gama alta 2011-V3. El costo-beneficio que ofrece es mayor que sus predecesores. Sobre todo si eres un gamer exigente te va a dar un rendimiento óptimo por mucho tiempo. A pesar de que ya tiene tiempo que está en el mercado, no ha disminuido su valor y desempeño en comparación con otros que casi duplican su precio solo por un pequeño porcentaje más de procesamiento. Si desean utilizar en sus equipos un arreglo SLI o Crossfire les recomendaría mejor el 5830 o equivalente porque los lanes de PCie que tiene este procesador no son suficientes. En cambio, si lo utilizan una sola tarjeta de video es más que suficiente. Otra cosa que hay que considerar es que a partir de este procesador, el empaque no incluye disipador por lo que buscar opciones de enfriamiento se vuelve obligatorio. Les recomiendo los AIO de enfriamiento líquido ya sea que vayan o no a hacer OC. En mi caso yo adquirí el Corsair Hydro 115i y no sube de 40°C a full (sin OC). Además es muy fácil de instalar.

Auch wenn das nicht Teil einer Produktrezension sein soll, möchte ich das vorweg kurz erwähnen: Ich habe zuerst eine gebrauchte CPU erhalten. Das Handbuch fehlte, und die CPU flog fast lose im Karton herum. Ich dachte mir zuerst, dass das normal sei, und ich unabsichtlich eine "Tray" CPU bestellt habe. Beim Auspacken der CPU fiel mir aber auf, dass im kleinem Loch der CPU noch ordentlich WLP Reste waren. Folglich war die CPU schon mal wo im Einsatz. Hab diese dann reklamiert, und per Expressversand sehr schnell 2 Tage später (!) eine neue CPU erhalten. Interessant war, dass das 2. Paket aus England kam, aber Deutschland noch welche auf Lager sein sollten. Ich befürchte mal, dass da offenbar nur Rückläufer lagernd sind. Der Amazon Support hat trotzdem da wieder Mal vorbildlich reagiert, und die Ware unkompliziert getauscht. ------------------------------------------------------------- Nun zur CPU selbst: Sie ist solide, die Tempverteilung ist ziemlich gut (delta vom heißesten zum kältesten Kern vl 4°c). Auch das OC Potential ist grandios!. Die CPU läuft bei mir auf 4,5GHz mit 1,185V, Vinput 1,88V, das ganze auf einem X99 A Board. Auch 3200MHz QuadChannel RAM steckt der Speichercontroller noch weg. Mit einem Noctura NH D15 bin ich da mit maximal 60% Lüfterdrehzahl auf knapp über 70°c in Prime27.9 Small FFT. Auch das ist ein sehr guter Wert! Alles in Allem ist der 5820k mit dem X99 Chipsatz das aktuell beste P/L Modell im "High End" Segment. Ich würde die CPU dem 6700k eindeutig vorziehen, egal in welchem Anwendungsbereich, sofern man den 5820k auch übertaktet.

Best 6 core processor if you are on tight budget/ could not afford to go for higher cores. I bought this for my rendering purpose and it is serving at its best. Go for this if you have CPU demanding tasks and tight on budget.

E' la entry level delle i7 socket X99, ma ha una potenza eccezionale ed è praticamente una 5930k con frequenze leggermente minori e meno linee pcie (40 vs 28), linee che comunque sono piu che sufficienti anche per sistema multi gpu a tre vie, e differenza di frequenza veramente minima colmabile con leggerissimo oc, ma il tutto ad un costo di circa 200 euro inferiore al 5930k. Notevole la differenza di potenza con l'i7 4790k per socket 1150, che mediamente si attesta oltre al 40% in default, se non che la maggior frequenza a default del 4790k lo rende piu veloce in operazioni come compressione e decompressione file e conversione file audio, ma questa lacuna è facilemnte colmabile, e anzi superabile con leggerissimo oc. Ancora non riesco a capire come questa cpu possa costare nemmeno 100 euro piu della 4790k................. Da mettere in conto che è una cpu con tdp da 140w, quindi se si vuole occare bene bisogna dotarla di un buon sistema custom di dissipazione come quelli a liquido. Attualmente la tengo a 4,08 con 1,15v, valori che ritengo piu che idoneii per un uso superlativo quotidiano. Con questi valori ho ottenuto un buon 1625 punti con xtu, con piattaforma su mobo asus x99 sabertooth e ram gelid super luce 3000mhz impostate a 2400mhz e windows 10 pro 64bit. Una cpu perfetta, che va bene per lavoro, per game e per divertirsi con l'oc. Personalmente per un uso esclusivo game consiglio la piattaforma x99 solo per sistemi multi gpu, con risoluzioni video da 2k 144hz in su.

Pros: - Calidad / Precio insuperable (a día de hoy) - Mucho margen para overclock sin problemas de sobrecalentamiento - Tras algunas benchmarks (hago render con vray), constaté que a 3.8 Ghz rinde igual que un dual Xeon E5 2620, y el procesador puede subir sin problemas hasta algo más allá de 4.5 Ghz con refrigeración por aire, sin necesidad de refrigeración líquida. Contras: - La caja de Intel no es apropiada para un producto delicado, expone mucho el procesador. A parte, el vendedor no incluyó papel u otros elementos dentro de la caja para amortiguar golpes y la caja llegó algo magullada.
