Galaxy S4 Exynos Octa-Core vs. Galaxy S4 Qualcomm Snapdragon! Which One Is Better



Today we will be talking about the differences between Exynos Octacore and the Qualcomm Quadcore processors used on the Samsung Galaxy S4.

Many U.S., Canadian, and European countries with 4G LTE ships with the Qualcomm processor while countries with no 4G LTE ships with the GT-i9500 Octa-core Exynos.

Of course, the Koreans get the best with both Octacore and 4G LTE. I believe this is due to the fact that 4G LTE frequencies used in Korea are easy to develop therefore used with Octacore. And also, there may be production issues with the newer Exynos processors.

I do expect that Note 3 will come out with the latest Exynos Octa-core even in the U.S. just like we’ve seen with Galaxy Note 2, which only ships with Exynos processors worldwide with LTE support. Again, this is due to the timing of phones shipped and unfortunately Galaxy S4 ships right when production of Exynos Octacore for all countries may be impossible.

That’s my theory.

But let’s take a close look at the Octacore and Qualcomm processors used in the Galaxy S4.

First the Exynos Octacore processor is made up of 4 high performance cores and 4 low performance cores. The idea here is that the Octacore is able to quickly switch between the 4 high performance cores and 4 low performance cores at the hardware level, saving you maximum battery while the Qualcomm does also throttle down but at software level, meaning more power wasted.

Now, both the 1.6Ghz high performance 4 cores on the Exynos Octacore processor and Qualcomm 1.9Ghz quad-core processor does fairly the same as far as raw CPU processing power goes. The biggest performance difference between the two processors is the GPU or graphics processor used.

The Exynos Octacore uses PowerVR SGX 544MP3 which is a newer version of GPU used on iPhone 5 with higher 533Mhz vs. iPhone 5′s 350Mhz. And yes, the PowerVR SGX on the Galaxy S4 is 50% faster than iPhone 5.

Now The Qualcomm uses the Adreno 320 GPU. I did a Quadrant benchmarking test between the two processors and the result was nearly identical.

With Antutu however, it clearly showed that the Exynos Octacore was faster by a whopping 25%.

Now to get into the nitty gritty I decided to dig deeper and test out graphics in more detail using 3DMark and Vellamo benchmarking apps.

With 3DMark, both Octa-core and Qualcomm performed near even with Qualcomm edging out the Octa-core by just a hair.

With Vellamo, the Octo-core did about 20% better.

So, what?

The bottom line is that these two processors are about even, I don’t actually see performance advantages to each, they may be near negligible for average consumer.

Samsung Galaxy S4 vs. HTC One: A clash of two Android titans

Two stellar smartphones are poised to battle for Android handset dominance.






If you're in the market for a new smartphone this year, chances are good you're seriously considering two highly anticipated handsets: the Samsung Galaxy S4 and the HTC One.
Both offer tempting helpings of powerful components, advanced features, and cutting-edge software.

Screen
Samsung Galaxy S4
Perhaps the most striking thing about the GS4 is its massive 5-inch HD Super AMOLED display. It also features a sharp 1,920x1,080-pixel resolution and a pixel density of 441ppi (pixels per inch).

HTC One
HTC gave the One a 4.7-inch LCD screen that's slightly smaller than the Galaxy S4's but boasts the same 1,920x1,080 resolution. As a result, the HTC One's display has a higher pixel density of 468ppi.





Storage
Samsung Galaxy S4
The GS4 comes in 16GB, 32GB, and 64GB configurations, though not for every market in which it'll be sold. Expect U.S. carriers to sell it in the smaller capacities, starting at $199 for the 16GB version and $249 for double that amount.
Unlike HTC, Samsung isn't a fan of sealing up devices; as a result, the Galaxy S4 comes with a microSD card slot that can handle up to 64GB of additional memory goodness for storing photos, videos, games, and apps.


HTC One
One consequence of the HTC One's beautiful , aluminum unibody design is that its chassis is sealed. Add in the phone's thin design, and you've got no room for a microSD card slot to add extra storage. HTC does its best to alleviate the situation by eschewing a 16GB model and packing the handset with either a sizable 32GB, or a whopping 64GB of internal memory. Significantly, the on-contract price of the 32GB One starts at the same $199 price of a 16GB S4.



Battery

Samsung Galaxy S4
Samsung equips the Galaxy S4 with a 2,600mAh battery that's user removable. It pops out when you remove the back cover, which makes swapping it out for a fresh one a simple maneuver. Samsung will also offer batteries that are compatible with wireless chargers.

HTC One
By contrast, the HTC One features a slightly lower capacity 2,300mAh battery, which is embedded. That means you can't remove it on the fly for a fully charged battery pack. Also, if the HTC One's battery fails, you'll need to send the device in for repair, or replace the phone for a fresh handset.


Operating system
Samsung Galaxy S4
Right out of the box, the Galaxy S4 will run Google's latest version of Android Jelly Bean, Android 4.2.2. That's great news for Android fans who can enjoy the all important bragging rights that come with owning a cutting-edge smartphone. However, Samsung does have its own user interface, formerly known as TouchWiz, so you're not getting a pure Android Jelly Bean experience.

HTC One
The HTC One uses the slightly older iteration of Jelly Bean, Android version 4.1.2. Nevertheless, the HTC One does support the enhanced Google Now search function, which can also be used as a dedicated widget on the phone's home screen. Of course, HTC layers its latest Sense user interface over Android, which many have blamed for holding up Android updates in earlier HTC smartphones.

Hands-on with the Samsung Galaxy Grand

Samsung Galaxy Grand GT-I9082


The dual-SIM Galaxy Grand is powered by the same dual-core chipset as the recently released Galaxy S II Plus. Switching from Exynos to Broadcom looks like a minor step down in terms of GPU, but as we saw on the S II Plus the superior power efficiency more than makes up for it. In fact, combined with the low (by today's standards) screen resolution this might turn the Galaxy Grand in one of the longest lasting smartphones on the market.

  • Quad-band GSM (SIM 1 & SIM 2) and 3G (SIM 1 only) support
  • Dual SIM stand-by
  • 21.1 Mbps HSDPA and 5.76 Mbps HSUPA support (SIM 1 only)
