Comparing HP OMEN 35L and Obelisk
Graphics card performance
Edge: HP OMEN 35L RTX 5080 Ryzen 9 Gaming PC
Product A features an NVIDIA GeForce RTX 5080 discrete GPU with 16 GB of dedicated GDDR7 memory, along with integrated AMD Radeon Graphics. Product B provides an NVIDIA GeForce RTX 2080 Super with 8 GB of GDDR6 dedicated memory. The graphics card in Product A gives you double the video memory capacity and uses faster GDDR7 technology. This higher memory bandwidth helps you run higher display resolutions and more demanding visual assets. Product B includes real-time ray-tracing support and VR readiness, but its 8 GB allocation offers less headroom for modern texture files. Product A holds the clear advantage in graphics capabilities.
Processor capabilities
Edge: HP OMEN 35L RTX 5080 Ryzen 9 Gaming PC
Product A runs on an AMD Ryzen 9 9900X3D processor with 12 cores, 24 threads, a 128 MB L3 cache, and boost clocks up to 5.5 GHz. In comparison, Product B uses a 9th-generation Intel Core i9-9900K chip featuring 8 cores and a base clock of 3.60 GHz. The processor in Product A provides four more physical cores and eight additional processing threads. Furthermore, its 128 MB cache size significantly exceeds the cache available on older desktop architectures. These specifications give you stronger multi-threaded computing and faster peak execution speeds when managing demanding computational software. Product A leads this round.
System memory
Edge: HP OMEN 35L RTX 5080 Ryzen 9 Gaming PC
Product A comes equipped with 64 GB of DDR5-5600 RAM out of the box. Product B includes 32 GB of HyperX DDR4-2666 SDRAM, which you can upgrade to 64 GB later. Starting with 64 GB gives you twice the capacity immediately, removing the need to buy extra modules to expand memory. In addition, the DDR5 standard in Product A transfers data at 5600 MHz, more than doubling the 2666 MHz transfer frequency of the DDR4 modules in Product B. This higher memory bandwidth ensures faster data access for memory-heavy applications. Product A takes the advantage for memory size and speed.
Storage capacity
Edge: HP OMEN 35L RTX 5080 Ryzen 9 Gaming PC
Product A delivers 4 TB of total storage across two 2 TB PCIe Gen4 NVMe M.2 SSDs. Product B provides a single 1 TB PCIe NVMe M.2 solid state drive. Product A gives you four times the storage space right away, allowing you to install multiple large programs and store large media libraries without running out of room. The PCIe Gen4 interface in Product A also supports faster sequential read and write rates than the standard PCIe drive configuration listed for Product B. Because of its larger capacity and dual-drive setup, Product A wins this round.
Chassis and weight
Edge: HP OMEN Obelisk RTX 2080 Super Core i9 Desktop
Product B weighs 23.2 pounds and stands 14.8 inches tall, with a width of 19.8 inches and a length of 20.5 inches. It features a tempered glass side panel that provides a direct window into the internal components. In contrast, Product A weighs 24.9 pounds and measures 8.4 inches wide, 16.7 inches high, and 16.3 inches long, with no side window listed in its specifications. Product B is 1.7 pounds lighter, making it easier to lift or reposition on your desk. Its tempered glass panel also lets you inspect your hardware without opening the case. Product B takes the edge for chassis design and weight.
Operating system
Edge: HP OMEN 35L RTX 5080 Ryzen 9 Gaming PC
Product A runs Windows 11 Home, whereas Product B comes pre-installed with Windows 10 Home. Windows 11 Home provides newer core features, updated scheduling algorithms for modern processors, and extended platform support. Windows 10 Home on Product B remains a stable operating system for everyday home use, but it represents an older OS version compared to the factory setup on Product A. If you want the newer platform out of the box without performing a system-wide upgrade later, Product A provides that foundation directly from initial setup. Product A holds the edge for its pre-installed operating system.
