CyberPower Infinity Xtreme Titanium GTX
The past few months’ machines have been filled with Ryzen and Coffee Lake processors, but CyberPower’s Infinity Xtreme Titanium GTX uses a Skylake chip – the Core i7-7800X. It’s a 6-core chip with Hyper-Threading, roughly matching the core spec of the mainstream Core i7-8700K, although it’s also lacking in some areas, with a lower clock speed and 8.25MB of cache compared to the 12MB in the i7-8700K. The
i7-7800X’s 140W TDP is also 45W higher than the Coffee Lake CPU.
However, CyberPower’s Skylake-X processor offers advantages in other areas. Skylake-X processors offer at least 28 PCI-E lanes compared to the 16 provided by Coffee Lake, which means more scope for extra graphics cards and NVMe storage. Choosing the i7-7800X also means you get the X299 chipset, which supports quad- rather dual-channel memory. It handles more SATA connections too, plus there’s more scope for upgrading. If you have a Core i7-8700K system then your CPU can’t go much further, but the CyberPower’s X299 motherboard can accept future CPU upgrades with eight,
12 or even 16 cores. Higher-end LGA2066 CPUs can also support up to 44 PCI-E lanes.
The CyberPower’s niche benefits continue to the MSI X299 SLI Plus motherboard. It has eight DIMM slots rather than four, and support for Intel Optane memory, although that’s currently of dubious benefit. There are also four 16x PCI-E slots. Meanwhile, the backplate has a clear-CMOS button, dual Ethernet ports and loads of USB 3.1 sockets, and there’s a second M.2 connector and a U.2 port free on the inside. There’s more room to grow here than on the usual Z470 systems we’ve reviewed recently.
There’s also 32GB of 3000MHz memory in the CyberPower, along with a capacious
500GB Samsung 960 Evo NVMe SSD. The Corsair RM750x power supply offers an 80 Plus Gold rating and a fully modular design, and the MSI GTX 1080 Ti card has a small overclock too, with the core raised from
1480MHz to 1506MHz.
The main factor that bumps up this machine’s price, however, is the full custom water-cooling loop. CyberPower has crammed an EKWB CoolStream SE
240mm radiator and two 120mm fans into the machine’s roof, and a small bracket at the front holds a tiny 60mm reservoir. The CPU is topped by a Supremacy waterblock, while the GPU has another piece of acrylic EWKB hardware. The smaller reservoir allows the entire loop to be installed in the top half of the case, which makes it easier to access the bottom half of the motherboard. It’s still relatively easy to access the spare memory slots too.
CyberPower has relied on the familiar Corsair Crystal 570X to house the system. Its side panels are made from strong tempered glass, and the steel skeleton is rock-solid, while the front and top panels are decorated with a honeycomb design that mixes a black plastic frame with fine mesh.
Smartly, CyberPower has installed Akasa Vegas fans – two on the radiator, one in the exhaust mount and three at the front. They feature rubber pads to reduce noise, and they also look the part, with a ring of red lighting around their border. CyberPower has done a solid job keeping the rig tidy too – there’s no cable braiding, but all the cable routing is discreet.
Finally, CyberPower’s three year labour warranty with two years of parts coverage is fine, although it’s a shame you only get a single month of collect and return cover.
This machine wins plaudits for its great design
The differences between 6-core Skylake-X and Coffee Lake chips are obvious in benchmarks. The relative lack of single-core speed, for instance, can be noticed in the image editing test. The CyberPower’s score of 51,003 is fine, but the stock-speed Core i7-8700K in the Chillblast Fusion Fireblade (see issue 176, p58) was quicker – and the Stormforce Crystal i7 8700K GTX 1080 (see Issue 177, p58) hit more than 65,000 points with the 8700K overclocked to 4.8GHz.
Meanwhile, the CyberPower’s six Hyper-Threaded cores returned a result of 405,041 in our heavily multi-threaded
Handbrake test. That’s another fine score, but both the aforementioned Coffee Lake systems were again quicker.
Pleasingly, the CyberPower’s overclocked GTX 1080 Ti card returned playable frame rates at 4K, never dropping below 37fps in any of our demanding tests, and that means it will happily handle VR headsets too. The SSD’s read and write results of 3,121MB/sec and 1,865MB/sec are fine too.
One advantage of the CyberPower’s lack of an overclock, of course, is cooling, especially with a custom loop at its disposal. The CPU’s peak delta T of 60°C is great, and the graphics card topped out with a chilly delta T of 36°C and a boost clock that topped out just below 1900MHz.
Those delta T results are better than the Stormforce and Chillblast machines, and we had no noise issues either. The CyberPower was barely audible when idle, and hardly any louder in a full-system stress test.
CyberPower’s decision to use 6-core Skylake-X silicon is curious when compared with the Coffee Lake chips deployed in rivals. The i7-7800X can’t match the i7-8700K in our benchmarks, although the X299 chipset and LGA2066 socket mean a more versatile motherboard and better upgrade options. For most gamers and generalpurpose users, Coffee Lake systems offer more immediate power for a lower price, while the serious content creators at which the X299 platform is aimed will likely want more than a 6-core CPU.
While the CPU choice is dubious, though, this machine wins plaudits for its great design, impressive water-cooling system and low-noise operation, as well as the versatility of the X299 platform. It’s clear that CyberPower has some expert PC building skills; it’s just a shame this PC’s core spec doesn’t quite hit the nail on the head.
