TV-like experience when we go to the Web or one o these major sports events. Ater all,

what un is it to watch a World Cup without hearing (and replaying) that crystal-clear

Gamers focus much of their attention

on achieving the best graphics with

high resolution monitors and the

latest, most powerful graphics cards.

All too often, the audio component is

ignored. Whether its the crunch of a

hard hit and the 360-degree crowd

noise in a sports game or bombsdropping and bullets flying in an FPS,

nothing makes a game come to life

more than an immersive surround

sound experience.

Typically, to get that kind of audio, you

need a 5.1- or 7.1-channel system

and the accompanying pile of satellite

speakers and jumble of wires to

carefully place all around the room,

making sure you can run wires to all of

them without creating a tripping hazard.

But the rockus 3D | 2.1 speakers from

soundscience, designed by Antec, can

deliver that 3D sound with just a 2.1

setup and some brilliant engineering.

The speakers feature 3Dsst tech-

nology, which uses a suite of DSP

algorithms to intelligently analyze

incoming audio signals such as

frequency, panning, and positioning of

sounds, and uses tools such as filtering

and phasing to pump out the sound

in a virtual 3D field, creating a spatial

aural environment with your ears at

the epicenterperfect for gaming and

watching movies.

Because gaming audio and music

are different animals, soundscience

built multiple audio modes into the

rockus speakers. The compact

remote control pod lets you easily

togg le between 3D and mus ic

modes, the latter delivering a stereo

signal for the ideal balance of highs,

mids, and lows.

The rockus speakers make the most

of their diminutive size. Compact

speakers often lose out on audio quality

due to cheap or weak construction,

but the rockus speakers can crank

out 25W per satellite with a 100W

subwoofer and are built with anodized

aluminum to cut down on vibration and

distortion. The subwoofer also boasts

passive radiator technology, enabling

it to deliver a wide bass range

especially compared to woofers with

a much larger footprintas well as

multidirectional output. They really look

and feel as great as they sound.

Great gaming speakers dont have to be

big, require numerous satellite speakers,

and cost an arm and a leg. For $199.99,

you can have an immersive 3D audio

experience with a compact 2.1 system.

Subwooer eatures support or three input types

or maximum versatility.

Control pod adjusts volume, mutes and toggles

between analog and digital input

For about $330, the Intel Sandy Bridge-based

Core i7-2600K quad-core processor represents

an excellent value or perormance-conscious

enthusiasts. With decent cooling, some tweaking

know-how, and a little bit o luck, an overclocked

Core i7-2600K can perorm on par with or even

better than Intels current agship 6-core processor,

the Core i7-990X.

The Intel XTS100H tower-type

cooler included with Socket

LGA1155 Core i5 and Core

i7 K series processors

does a respectable job o

keeping CPU temperatures

in check. Using this stock

cooler, we were able to

push a Core i7-2600K to over

4.6GHz with perect stability

and zero throttling.

BYMARCO CHIAPPETTA

There is a widespread miscon-

ception that Intel has locked downnon-K series Sandy Bridge-based

processors to prevent overclocking.

The conusion partially stems rom

the act that Intel has integrated

a PLL/clock generator, which

historically used to reside on

the motherboard as a separate

component, into the 6 Series chipset

die. That PLL is used to derive the

deault 100MHz BCLK o Sandy

Bridge-based processors, but due

to a number o actors, its speed

cannot be increased much past thestock 100MHz. Reports vary on the

max BCLK users have been able to

hit reliably, but 103 to 105MHz is

usually possible. Anything higher

than that is a crapshoot.

In conversations with represen-

tatives rom Intel, though, the com-

pany has stated that the limited

reedom with regard to BCLK

adjustments may change with uture

versions o the 6 Series chipsets

and newer Sandy Bridge processor

revisions. For now, overclocking viaBCLK adjustments will yield minimal

benefts, but there is hope this will

change at some point in the uture.

Overclocking isnt completely out

o the question with non-K series

Sandy Bridge-based processors,

however. Non-K series chips that

support Intels Turbo Boost technology

are actually somewhat unlocked,

just not to the extent o K SKUs. Intel

calls the chips limited unlocked.

What these CPUs allow you to do

is increase the peak Turbo Boostrequency by up to our speed bins.

For example, i a Core i5-2500

has a deault clock o 3.3GHz and

a peak Turbo Boost requency o

3.7GHz, increasing the peak Turbo

multiplier rom 37 to 41 will result

in a maximum requency o 4.1GHz.

Thats nowhere near as high as K

series processors have been known

to overclock, but speeds greater than

4GHz are nothing to sco at.

No K? Still (Sort O) OK!

In addition to adequate cooling,

overclocking Sandy Bridge-based

processors at this time requires one

more thing: a P67-based motherboard

designed with overclocking in

mind. There are a number o quirksassociated with overclocking Sandy

Bridge-based processors, and i the

motherboard isnt designed to cope

with them, keeping a system stable

will be difcult.

* Lower scores equal better perormance.

We ran a handul o popular

applications and benchmarks

to see just how much additional

perormance we were able to

extract rom our overclocked

Core i7-2600K-based system.

In the chart presented here, we

have benchmark scores rom

the ollowing three test-bed

confgurations: the stock Core

i7-2600K, the Core i7-2600K

overclocked to 4.64GHz, and Intels

current agship Core i7-990X six-core

processor running at its stock speeds.

The numbers tell an interesting

story. Obviously, overclocking the

Core i7-2600K to 4.64GHz re-

sulted in some large perormance

gains. The overclocked processor

outpaced its stock counterpart by

margins ranging rom 13.3% to

42.47%. The smallest gains were

realized in the SiSot Sandra

memory bandwidth benchmark

and in the less taxing LAME

MT encoding tests. The gaming

tests and processor-intensive

rendering benchmarks showed

the largest improvements.

Comparing the perormance o

our overclocked Core i7-2600K

to the Core i7-990X processor

proves that you dont need to

spend $1,000 on a CPU to have the

astest rig on the block. Although

it wasnt a clean sweep, the over-

clocked quad-core Core i7-2600K

was aster than the six-core

Core i7-990X in our o the eight

benchmarks we ran, and in three o

the tests where the Core i7-2600K

trailed Intels agship, the delta

separating the two processors was

less than 5%.

Pete F. asked: I have a question oryou guys about SSDs, but not the tradi-

tional SATA-based drives that everyone is

clamoring over. I do a lot o video production

as a side business o mine, and I could really

beneft rom the screaming ast speeds o a

PCI-E SSD card. Ive been watching various

products come to market, rom Fusion-ios

ridiculously expensive blades to the more

reasonably priced products, such as OCZs

Z-Drives and RevoDrives.

Whats your opinion on what currently isthe best value in PCI-E SSDs? Do I really need

something with SLC, or will MLC work or what

Im doing? Im not so concerned about price, but

Im defnitely not interested in dropping a ew

Although the OMAP 5 platform contains several architectural improvements

versus the OMAP 4 platform, Carlson says its important to keep in mind that

the two platforms are architecturally related, which ensures compatibility.

Carlson says the upgrade to the Cortex-A15 processors along with the

addition of the Cortex-M4 processors provides OMAP 5 a strong upgrade in

processing power and efficiency over the OMAP 4 and its Cortex-A9 processors.

A15 brings a lot of advancements in being able to do more in each

clock cycle, Carlson says. You cant just compare clock cycles. Its a big

boost in performance.

TI claims a 60% average power reduction in the OMAP 5 vs. the OMAP

4 when performing the same types of tasks. Carlson says much of the

power reduction occurs because the OMAP 5 uses a 28nm fabrication

process, while the OMAP 4 uses a 45nm fabrication process.

That gives us about a 30% reduction in power alone, Carlson says.

Internal caching lets us reduce power even more. There are a lot of things

we are doing behind the scenes to reduce power. I have all of this per-

formance on demand when I need it, but I also can use that overhead to

reduce power usage.

OMAP 5 also takes advantage of the third version of TIs SmartReflex

technology, which manages power conservation. (OMAP 4 used the

second version of SmartReflex.)

OMAP 5 will be available in two configurations. The OMAP5432 will

be aimed at mobile computing and other consumer products, while the

OMAP5430 should appear in smartphones and tablets. OMAP5430 is

smaller and uses less power than OMAP5432, allowing it to fit better in the

smartphone and tablet market.

The whole key for this architecture is to do things as efficiently as pos-

sible from a power perspective, Carlson says. Its about doing all of this

from a very low power budget.

The primary difference between raw NAND and Microns

ClearNAND is the placement of an ECC (error-correcting

code) controller on the NAND die. With raw NAND, the

host processor performs all of the required tasks, such

as supporting ECC and block management, internally.

By moving the ECC controller onto the NAND die with

ClearNAND and by using new error-correction algorithms,

ClearNAND can provide greatly improved performance

over raw NAND, Microns director of NAND strategic

marketing Kevin Kilbuck says. With the improved ECC

under ClearNAND, he says customers who have hit a brick

wall in terms of performance using raw NAND will be able

to take advantage of ClearNAND.

We have customers today who will use our 25nm

ClearNAND who cannot use raw NAND because of

ECC issues, Kilbuck says. With our error-management

algorithm, we can improve endurance over what raw

NAND can do.

Scaling NAND into finer geometries allows for higher

capacities and lower costs but also requires more error

correction. NAND endurance also degrades along with

manufacturing process shrinks.

As shown in graph A, as the geometry shrinks, the number

of bits required for ECC rises, and the number of P/E (program/

erase) cycles the NAND memory can endure declines.

The bits become more tightly packed as the NAND scales

down into finer geometries, meaning the memory cells are

moving closer to each other, which causes more interference

and crosstalk. You can see the smaller gates

in each geometry in the photos below.

When the manufacturing process shrinks,

the memory transistors have fewer electronsper floating gate, which leads to more bit

errors. The increased RBER (raw bit error

rate) requires more bits dedicated to ECC.

Consequently, the number of logic gates

dedicated to ECC in the memory must be

increased, too, as shown in graph B. For

example, 16-bit ECC (marked as BCH t=16

in the graph) requires about 80,000 gates. A

60-bit ECC would require about 300,000 gates.

Were starting to reach the effective

limit of what standard ECC can do, says

Kevin Kilbuck, Microns director of NANDstrategic marketing. Its starting to limit the

adoption for NAND in some environments.

. . . Clear NAND can alleviate a lot of these

headaches. By using these tools, we can

improve the endurances quite a bit over

what the raw NAND can do. We can cycle

a lot more data through before we wear out

the NAND.

The ClearNAND controller takes over the ECC and uses

improved algorithms for better endurance.

Kilbuck says that despite the drawbacks with continued

scaling, the current benefits still greatly outweigh any problems.

We do it for cost reasons, Kilbuck says. By scaling, we

offer new applications. NAND continues to displace other

forms of media. . . . ClearNAND helps . . . but the scaling wall

is coming. Were getting to the point where we can count the

number of electrons in each cell on our fingers and toes.

Even though advancements in NAND technology, such as ClearNAND, will lengthen the lifespan of the traditional

NAND design, Kevin Kilbuck, Micron director of NAND strategic marketing, says that the technology will eventually hit

a limit because the floating gates simply cant be made any smaller. Currently, Micron is exploring two future memorytechnologies, 3D NAND and Cross Point NAND.

3D. By adding multiple layers to its NAND cells, Micron could potentially increase densities without having to further

scale down the size of the floating gates.

With 3D, wed build layers of transistors vertically, Kilbuck says. It sounds easy, but its not. Its very conceptual at this

point. . . . We learned a lot of these 3D techniques with DRAM, and we may now apply it to NAND.

Cross Point. A Cross Point design potentially would provide greater density with both vertical and horizontal storage.

With Cross Point, we place the storage elements in an X-Y array, Kilbuck says. The storage element would have to

be made very small and power-conservative.

Microns research into these memory technologies will continue, Kilbuck says, but the company isnt ready to give up

making additional improvements to NAND yet.

There is nothing in the next five years that will approach the cost [value] of NAND, Kilbuck says. NAND still has a lot

of headroom, even if we do nothing more [in terms of NAND research.] Source: Micron

One area where ClearNANDs architecture allows it to experience greatly improved performance is in how ClearNAND

handles a process called Copyback, which involves moving data from one channel (or package) to another.

During Copyback with raw NAND, the host controller issues a read to one of the NAND die, controls and checks the

ECC, and then programs (writes) the data back to another NAND die. The external bus is tied up with moving data during

the entire operation.

With Enhanced ClearNAND, the host controller still handles Copyback. However, ClearNANDs built-in ECC controller

handles the ECC controls, meaning data can be moved from one die to another without tying up the external bus. The

error correction can be completed internally.

In a large SSD system (shown here), the operation of moving data from one die to another (shown with green arrows)

can be performed internally, with up to four simultaneous operations per channel, freeing up the external bus. If the data

must be updated or moved between packages or between channels, the host controller and external bus then can be used(red arrows). By freeing up the external bus and using it only for particular types of data movement, ClearNAND greatly

improves overall system performance.
