Warning - This is merely a homely analysis, only expressing some benchmarks. Do not be offended or offend.
This review follows on from numerous discussions about what is the best option, FX 8320/50 or 3570K (4670k), seeking to offer a reliable and homely analysis, far from any economic pressure, which as we know, often is exerted on the best known "reviewrs".
It´s important to understand the characteristics of the companies when we analyze both material´s, AMD is tiny compared with Intel, the Intel budget just for ID, is probably three times the total annual budget of AMD, AMD is slightly larger than the Nvidia .
Therefore, we have to take into account this aspect to moderate the demands / expectations.
The tradition has almost always been, Intel with top machines and top price matching and AMD looking to be strong on price / performance market.
With the arrival of 1150, very little has changed in terms of performance, so, this analysis remains valid to compare the replacement of 3570K, 4670k, since the differences between them aren’t many.
The systems under consideration are composed:Intel
MSI Z77 GD65;
SSD OCZ Vertex 2 RAID0;
SSD OCZ Vertex 2 RAID0;
Both systems well composed and ready for OC:1155
I5 4670k + MSI Z87 G43360 USDAMD3+
FX 8320 + GA 970a UD3/Asus M5A97 R2.0250 USD
So we are talking about a difference of 100 USD.
It is enough for a greater graphic´s card / SSD and so on.
Configure the Intel platform is very simple , everything follows the " Plug and Play "logic.
Essentially, the symbol K , identifies the processor with unlocked multiplier , so simply and roughly:
- switch multi to the desired speed;
- Disable Turbo and energy saving options;
- Increase Cpu Core Voltage; System Agent Voltage e Cpu PLL;
- Memory, plug and play logic again if they have XMP.
No tricks , simple and effective , the settings used in OC 4500mhz :
Cpu Ratio - x45;
Cpu Core Voltage - 1.19:
Cpu Pll - 1.6
Cpu I/o - 0.95;
System Agent Voltage – 0.925
An Overclock of this kind requires proper cooling , tapping the need for an investment of around 35-40usd.AMD:
After a few minutes of analysis, it comes to mind that we are in the presence of a more hardcore platform, the settings are not as easy neither the results, although everything works quite well.
The FX are all unlocked, however, for OC, it’s not just change the multi, "et voila".
You need to find the balance between CPU multi and Bus Frequency, by just changing the multi, it may be required higher voltage for the desired speed than combining multi + Bus, reminds me of the 1366 platform.
Therefore, it is necessary to change:
- Cpu Multi;
- Cpu Bus Speed (200-230);
- Cpu Vid (até 1.55);
- Cpu NB Vid (até 1.35);
- Cpu Pll + ;
- DDR Vtt + ;
- Amd cool and quiet; Amd APM; AMD C6/C1E – disable .
Settings used OC 4500mhz:
Cpu Multi 21x
Cpu Bus Speed 215
Cpu Vid 1.5
Cpu NB Vid 1.3
Cpu Pll + 0.10
DDR Vtt + 0.05
4500mhz seems to me the best compromise and what can be expected with a medium range cooler.
Summarizing the steps to OC:1)
increase the multi to realize the maximum stable mhz with stock voltage;2)
finding the maximum point, increasing the bus speed to understand the effect beyond MHZ achieved only by growing multi;3)
Balance found , increase various voltages and repeat the process (multi + + Bus)
Take into account that, from a certain point, it will be beneficial to maintain the lowest multi, increasing only the CPU Bus
The temperatures should not pass the 72 at core.
4500mhz OC temps
Intel 1.211 vcore - 58º
AMD 1.512 vcore - 49ºVo data RAID0
One of the most criticized aspects on AMD platform is the RAID 0 performance.128
