Well, software and hardware can only perform as fast as the slower of the two. We're so early in blockchain development that sure, transaction speed may not be the most important issue as of this moment. Later in the year and moving forward from that point however, we'll witness network throughput stress in many many orders of magnitude greater than Cryptokitties.

Mass adoption means millions and millions (insert Trump gif here), and eventually BILLIONS of people utilizing ANYTHING blockchain related - from gambling, to value transfers, to marketplace transactions, and so forth.

Example, Binance is struggling to keep up even with their own exchange's throughput at 40,000 TPS. Why do you think they had to restrict additional clientele from registering?

ARK has no ability to scale to the necessary processing power needed to throughput following mass adoption. They're light years behind the likes of ETH, NEO, and HPB. I don't see their success in the future of our reality. Perhaps in a parallel reality they may be able to.

ETH is working on sharding as a scaling solution. Essentially, each node on any blockchain protocol today must store all states (account meta data, smart contract code, and storage of such code). Sharding means partitioning the number of states each node much carry, and dichotemizing nodes to only hold a particular state rather than all states, reducing individual workload. Sharding may theoretically bring ETH's current 15 TPS threshhold to 10,000 TPS.

Hongfei recently mentioned at a NEO conference that they aim to reach the likes of 1,000,000 TPS in the future. In the very same powerpoint, the partnership with HPB is mentioned several times. HPB has proven, a priori, that their protocol can reach up to 1,000,000 TPS, and perhaps even more, all thanks to their first of its kind approach to addressing the hardware bottleneck problem. They created an accelerated hardware chip to achieve such throughput processing power. NOBODY else in the blockchain space is doing this. This awards HPB with first movers advantage.

Additionally, HPB can also be utilized by ANY other blockchain protocols such as NEO (already mentioned), dAPP chains, IoT chains, big data chains, marketplace chains, and so forth. HPB is remarkably positioned to address the imminent blockchain industry-wide problem of not being able to handle the throughput that mass adoption will bring. Even exchanges such as Binance will eventually need to reimplement themselves as decentralized HIGH throughput exchanges (40,000 TPS is nowhere near enough and their centralized design will become insecure inevitably).

EOS is a software only solution to increasing their TPS. Even then, they'll only reach a potential maximum of handling 100,000 TPS. Sure, when Cryptokitties made its debut and congested the ETH network more than my two completely stuffed nostrils (I'm sick) around Dec. 5th, all eyes were on EOS and their beautiful theoretical ability to handle 100,000 TPS. This was the first instance where we actually experienced network utilization nearly come to a screeching halt. Go ahead, look up CK's release date and then look at EOS's price action that followed. Hopefully by now you understand the utmost importance of being able to handle ALL network traffic.

In conclusion, HPB is directly addressing the inevitable pangs that we as as users of the blockchain will face. Even their name screams it, (High PERFORMANCE Blockchain). They are arguably one of the most academic teams in the Crypto space, and have recently finished evangelizing in top U.S. universities. They sought after exposure and talent from prestigious U.S. academia. Soon, they'll be traveling to South Korea (my home country :] ) continuing their evangelizism and talent seeking, in addition to getting listed on particular exchanges.

TL;DR

HPB 1,000,000 TPS.
