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.

Per­for­mance

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.

Con­clu­sion

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.
