A newly published analysts report has investigated the potential performance of the the upcoming processors from Nvidia and Qualcomm and concluded that the Tegra 4 will outshine the Qualcomm Snapdragon 800. However the caveat is that the conclusion is based on projected performances and manufacturers benchmarks!
Since the real chips aren’t out yet and can’t be tested or benchmarked, the analysts at Linley Group have written a report based on performance data released by Nvidia at the Mobile World Congress in Barcelona along with projections about the Snapdragon 800′s performance based on the Snapdragon S4 Pro.
Running at full speed and without worrying about power consumption the report concludes that the Tegra 4 will beat the Snapdragon 800. To get an estimate of the Snapdragon 800′s speed, the team took the benchmark data for the Snapdragon S4 Pro and then factored in the speed bump from 1.7 GHz to 2.3 GHz plus added a 10% performance increase due to improvements to the Krait 400 core.
But I question the findings of the report. The Snapdragon 600 is already proving to be a formidable processor. Although recent benchmarks have shown that the Tegra 4, which scored 16,436 in the general-purpose Quadrant v2 benchmark, is faster than the Snapdragon 600, which scored 12,417, the Snapdragon 800 should be faster still. Here is some maths. The Snapdragon 600 is running at 1.7 GHz and the 800 should run at 2.3 GHz. Taking the 12,417 result for the 600 and factoring in the clock speed difference means that the 800 should score over 16,799 without considering any performance gains in the Krait 400 core.
Ultimately the only way to really see which CPU will be faster is to wait for both processors to hit manufacturing and to trickle down into real world devices. Even if the Tegra 4 is faster than the Snapdragon 800, the report notes that Qualcomm’s chips are designed for power efficiency, whereas Tegra 4 delivers high performance but with high power consumption. If that is true then the Snapdragon will challenge Tegra 4’s performance in smartphones, but in tablets, Tegra 4 will most likely win.

T4 will be a powerhouse, just like other 4XA15 chips (Exynos Octa of course), but power efficiency is THE key performance. Phones will only have Tegra4i obviously, with Tegra4 for tablets, whereas S600/800 and maybe Exynos Octa will be usable in both categories.
We haven’t even seen SD800 benchs or Adreno 330 capabilities, plus the Tegra4 scores were on a heat-sinked wall-powered tablet that was probably overcloked to crap for attention. To make things worse, if the 4 is too hungry for phones, there’s no way in hell nVidia will be competitive with the 4i, which is A9 rebranded.
I agree, I voted you up. But you are wrong about the overclock, I saw a video with an Nvidia rep standing at the demo board, and he said the clock was normal.

Quadrant is a device benchmark, not a SoC benchmark. When will “experts” understand this?
Comparing 2 SoC, both of which are not available and based on a sh!t benchmark tool. How more stupid can it get?
The tegra 4 was benchmarked by reviewers, albeit on non-production devices. They were not heat sinked, but rather in unlabeled devices. The display models were in clear glass housing, which would give different thermals but the devices tested by engadget were unbranded ten inch plastic tablets. The benchmarks should run pretty close to how these devices performed.
As for the qualcomm, they have benchmarks for the 600, which showed tegra beating it by 1/4 to 1/3rd. Clock speed isn’t a linear performance boost, as you know Gary, so it is safe to say the tegra is faster. However, nvidia has some challenges on their hands with battery life, due to the 4+1 with high OP clocks and non integrated Ltd.
T4 and T4i will sweep the floor with any SnapDragon :) Tegra FTW!
nvidia wipes their asses with qualqomms shitty low performing chips
qualqomm ahve the worst developer support as they dont provide and drivers or libs for armv6 chips worst company ever on the other hand nvidia provides all drivers and libs for their tegra socs
*sarcasm on* Yea, nvidia has the best developer support ever. That’s why the HTC One X was one of the last phones to get proper CM10.1 (which is still very buggy) and that’s why even Linus Torvaldis flipped them off. *sarcam off*
Set your facts straight.
Exynos is even worse. I don’t know what that troll above you is talking about.
Lol what a fail. Let me debunk this right now.
First of all, the improvements from the Krait v2 cores in the S4 Pro to the Krait 300 cores in the S600 is about 15% at the same clock frequency, and the Krait 400 cores have a couple more improvements so the Krait 400 cores should be close to 20% faster than the S4 Pro at the same clock speed NOT 10% like they did in the “comparison”
Also, These benchmark scores don’t account for the 50% improvement of the Adreno 330 vs the Adreno 320.
This is a major fail and I can definitely see the Snapdragon 800 outclassing Tegra 4 but only time will tell.
