I have a i7 4790k and a R9 390 gpu my system only cost 1000 dollars. i don't think 800 dollars is going to build a good computer when you can spend 200 more on an i7 if you really want a true computer CPU: i7 4790k 319.99USD GPU: XFX R9 390 DD 319.99USD RAM: 16GB 1600Mhz 79.99 SSD: 512GB 129.99USD PSU: 650watt gold 69.99USD yes i know my cost does not even out but i paid for a case and other things as well. my rig will last me for 2-3 years with out upgrading. "R9 490" So happy for this i am thinking about selling my R9 390 and buying the 490 i'm thinking about the 490x :D but back to the topic. intel is worth 55.4 billion so they can build better chips. AMD is worth just under 4 billion. come on guys go with the smarter choose if you are going to build a rig spend the 200 extra and buy an i7. dont give me they shit about how it cost 200 dollars more for an i7. but you have to know if you don.t put a i7 in your computer you will not be playing any upcoming games and less play time do to heat... the i7 always is the smarter way to go.
I can't really say you can make a comparison givin' the i7 is $200 more expensive. AMD has been budget for a while, FX is definitely budget performance. Compared to and i7. It's cheaper than an i5 even, but at $160, it maybe better to go i5 for a little more, that would be a better comparison. Yes Intel is better in this case, but it's $200 more dollars. I can say they are the same class, but they are on completely different levels. It's like a budget verses a high class elite CPU. If you can't afford a $1,500 computer, then you can build a FX system for like $800. Budget. That "typical power consumption" also seems ridicules. If you overclock it ya. I guess you probably will though, but then what with the i7! You are going to over clock that too I'm sure. I'm going have to look that up, seems unfair. These guys are known for a bias and incorrect info on certain pages. I don't know. Maybe.
well, I always used Intel Processors :) day have been good... now I have one toshiba L70-B-10R (i5-4200U AMD R7-200M) If Intel is the best why that dont give 70fps... but only 30FPS... if games only use 1/2 cores why buy a multi core... this is my 4th computer, 3 of them notebooks... My fist notebook with one Centino 1.6 with 64MB!!! (ATi R9700) dedicated grafics card that let me play every game for 5 years... Quality is quality but you all must remember one thing, games are optimizided only for some products and why... for sell at most priced :) why create so many processors with so many references if we only need one... ya!!! companies need to sell to stay on road... another thing I dont pass my all life playing :) ya I know... every person have the right to do what ever...!!! the same of what we have to buy or not :) end of game insert coin :)
Here in Canada the AMD FX8350 is priced at 259 and the Intel I7 4790k is at 559 so i don't really see that the Intel offers anything close to double the performance and will most likely go with the AMD in my next build ( the newer generation of Intel is quite a bit lower so that is still in consideration but this older generation is out of contention)
Casual Gaming= AMD Everything else = Intel Fixed that for you. Having owned both an AMD 8350, i5-6590k and now owning a i7-6790k, without a doubt stronger cores make a huge difference in a good majority of games. Obviously if you only play Call of Duty, Battlefield, puzzle games, old games and other unmodded AAA titles (GTA, Fallout/Skyrim to name a few) then you won't see a difference, but RTS games, modded games and a good amount of indies are largely CPU intensive...hell even the Sims has a distinct difference in performance between AMD and Intel. I used to love AMD when the only game I was really playing was Team Fortress 2 and a little Fallout New Vegas here and there. 200 games later and I'm glad I switched to Intel.
Some games are developed for Intel and some for AMD, if the game needs a high rendering time and process in quantity AMD its not a good option, that is why it is not good for render. CPU is used to render things that appear in screen, fast loading of data in RAM, the GPU is used to load textures on objects, i believe that massive processing its not recommended for AMD... but, in general its pretty good, the cost benefit is better in AMD than Intel, for Gaming, but, when you really need the processor AMD can't handle so well, so i recommend AMD for Gaming and Intel for rendering, things are just about cost benefit or user expectation, if money its not a problem Intel, otherwise AMD xDDD
Games like Planetside 2 are CPU intensive, and the #1 question asked in global chat by hundreds of thousands of users so far is "Why is this game so slow, my PC is new?" and then everybody always asks what processor they have and the answer is ALWAYS AMD. AMD works great in games that rely heavily on the GPU (graphics) only, but some games also require that the CPU do some work, and when you play them with an AMD you'll really really notice how far the CPU lags behind Intel. Generally the rule is that if you're a gamer, you want Intel, because when games do require CPU, then you'll find that your AMD is lacking, where an Intel CPU would deliver.
WHAT??. "Games = Amd"?, Intel cpus are much much better at gaming than Amd's , because amd cpus sucks when 4 or less cpus are used at the same time, but when you play games, only 2 or 3 cores will be used, so amd cpus are not good at gaming but rendering etc, because then it can use all of its cores your statement is super wrong
That's why i said it's buggy. It's more accurate when the CPU is on full stress or load. Also, what im i doing on the picture above? xD
Games = Amd Rendering, 3D work, etc... = Intel but intel now its awesome for gaming too since last 2 years, i can tell its better than AMD in some cases, so Intel its expensive and very good for gaming and excellent for rendering
Yeah ummm no. A. This game is garbage and doesn't use the threads like a proper DX12 game should. B. API tests prove different. No one is saying a AMD is better than Intel, but every reviewer loves to stomp on them. Competition is a good thing. However, so many people have fallen into the Intel is king mentality. Just like in the Athlon days you guys still won't admit AMD is a strong competitor when they finally get their head out of their ass.
DX12 is going to be a game changer as the FX isn't much behind this $400 chip. Single core performance will be a thing of the past. The FX will not surpass the 4790, but for less than half the price will keep up pretty damn well.
This is also ANOTHER myth. The core temps are not read faulty they just aren't accurate until about 30*C. The CPU socket temp which is what matters in power consumption is accurate 100% of the time.
I love how many ignorant fanboys there are down here...
i dont like monopoly.. i am not a fanboy, i am a wise costumer.. and i demand competition on both sides.. just because one game shows bad dx12 performance on FX cpus doesnt mean they should be thrown away.. i wanna see whats more in store for te FX owners.. i am sure there is something worthwhile... 6300 is a good bang for the buck processor and i do most of my rendering on it.. i wanna squeeze more out of it before i say good bye
Why? You're totally fine with your 4690K, is almost twice more powerful. So why worried about your FX6300?
yep, seen that... if that happens to be true then the people who own FX processors are totally fucked... i own a 4690k and a 6300... and i wish to squeeze a lil more out of the 6300..... i hope microsoft does somthing abt this
Or not... Source:
That temp is wrong. The termometer on FX CPU's is buggy and give false positive.
DX12 might change things since it will spread load to all cores making AMD 8 cores relevant again
$=AMD Gamers prefer I-7 4790 Everyone else AMD FX8350 Since I don't game, guess which one I prefer?
A few thing's need to be corrected, The average power usages for the AMD FX8350 are well out of preportion, CPU Boss isn't even taking into consideration the power saving features on offer by the cpu manufacturer and the motherboard manufacturer. You can stil utilise this cpu chip effectivelly if your smart about it. AMD Cool n quiet cuts the cpu frequency right down when the cpu is idling i have the FX8350 and i am only using firefox and at the moment the cpu is operating at 1.4 ghz when idling this therefore means your not going to be pulling out the full 125 watts for stock clocks, well under to be precise. So really some revised corrections do need to be made. Motherboards do have advanced power control utilisation for cpu chips these days too.
Tek Syndicate did a video comparing an Amd rig to a Intel/Nvidia rig and Crysis was the only game Amd had a higher frame rate In.
The fact crysis 3 scales to 8 cores and amd cpus still lose is pathetic.
